Joshua,

X = 3 (answer)

Here are the solution steps:

10x minus 3x equals 20 plus 1

10X minus 3X is 7X (right?)
20 plus 1 is 21 (right?)
therefore:

7X = 21

now divide both sides of the equals sign by 7

7X divided by 7 equals 21 divided by 7

7X / 7 = 21/7

X = 3 (answer)

2x plus 5y equals 7 3x plus 6y equals 3


1) 2x + 5y = 7
2) 3x + 6y = 3

I'm going to use the method of elimination to solve for x and y.
Multiply 1) by 3 and 2) by 2 to allow the x's to be eliminated.

1) 6x + 15y = 21
2) 6x + 12y = 6

Now subtract line 2 from line 1.

0x + 3y = 15
---- ----
3 3 divide both sides by 3 to get y by itself.
y =5.
Substitute into 1) to calculate x.
2x + 5(5) = 7
2x + 25 = 7
2x + 25 -25 = 7 - 25
2x = -18
---- ----- divide both sides by 2 to get x by itself
2 2

x = -9

Check by plugging in answer into the other equation, in this case 2)

3 (-9) + 6(5) = 3
-27 + 30 = 3
3 = 3
We did it correctly and checked to prove that we did it right.

Good luck.

I want to create an if else statement with regards to this problem for ms excel 2007. the conditions are if month>=3 plus 1/2 but if not then minus 1/2.


It seems to have botched your sign before the =3 but lets say that you used "less than" or equal to 3.
(if you used Greater Than, then simply replace "less than" with "greater than" in the example here)

The easiest thing to do is subtract 1/2 no matter what and then say if month is less than or equal to 3 then add 1.
this way, if the month is NOT less or equal to 3, it has already subtracted 1/2, satisfying the "if not" part.
If the month IS less or equal, it adds 1 which compensates for the 1/2 we already subtracted, plus another 1/2 giving an end result of plus 1/2.

This makes it a simple, single if statement that is satisfied in the other direction without having to overcomplicate the issue.

One number is 11 more than another number. Find the two numbers if three times the larger number exceeds four times the smaller number by 4.


Do you need help doing your homework?

If so, here's a first attempt. It may be correct, and it may not be.
It's up to you to understand the process, and to make any needed corrections.

X minus 11 equals Y.
So, X is larger than Y.
So, 3 times X minus 33 equals 3 times Y.
Thus 3 times X equals 3 times Y plus 33.
Also, 3 times X minus 4 equals 4 times Y.

So, (3 times Y plus 33) minus 4 equals 4 times Y.

Thus 0 times Y plus 29 equals 1 times Y.

So, Y equals -27.

6x squared - 10x =0


Factor out 3X
3X(2X-5)=0
The expression is equal to zero if one of the factors on the left side equals zero.
1st solution: 3X=0, thus X=0
2nd solution 2X-5 = 0 if X=5/2

I have an equation: 6-2(5x-8) = 3x - 4. I need to


Hello,
I will not ask what you want to do with the equation I will answer your question about the equal sign. Press [2nd][CATALOG] you access the catalog of available commands. The equal sign is near the bottom of the list. So it is faster to scroll up from the top, and keep scrolling up till you reach the =. Select it and press [ENTER], it will echoe at the place where the cursor was before you press [2nd][CATALOG]. Complete your equation.

Hope it helps.

3x+8y+ 13z=357.5 16x+9y=326


This is easy. First these brackets ( ) have a three numbers followed by an x y and z, the brackets mean we should multiply the like amounts: but first lets group like amounts by adding them up 3x+16x+6x= 25x then 8y+9y+11y=28y, now z...13z+14z=27z now the otherside of the equation which is always after the equal sign is 326+453=779, so now it is more simplified by combining like amounts:so now we have 25x+28y++27z=779 so now we must balance both sides of thr equation, what we do to the left side of the equal sign, we must also do to the right side of the = sign, so we need to get x by itself, so we minus 25 and are left with just an x, then if we take 25 off of the other side of the = sign, we must take 779-25 so now x is on the left side by itself then the the right side is 754, so now the x is solved X=754, then you do the same for y and z.

7x-3+3x=-53 what is the value of 4x+9


7x-3 + 3x = -53
7x + 3x - 3 = -53
10x - 3 = -53
10x = -53 + 3
10x = -50
x = -5
Therefore 4x + 9 is equal to 4 times (-5) plus 9
-20 + 9 equals -11
