5x + 7 = 45

5x = 45 -7

5x = 38

X = 38/5 = 7 3/5 or in decimal

X = 7.6

Or this could be a straight line equation of y = mx + c

Were y = 45 m = 5 = gradient of 5. Through the point of origin c = 7 at x =0

To evaluate the expression you need the value of x.

To solve you do as follows

ln(5x)=12/4=3

Take the exponential of both sides of ln(5x)=3

e^(ln(5x))=5x=e^(3)

This gives**x=(1/5) e^(3)**

To solve you do as follows

ln(5x)=12/4=3

Take the exponential of both sides of ln(5x)=3

e^(ln(5x))=5x=e^(3)

This gives

Write the equality in the form y=(5X+3)/(4X-5). Insert parentheses to ensure a correct result.

- Multiply both sides of the equality by (4X-5). This gives (4X-5)y=(5X+3).
- Open the parentheses as 4Xy-5y=5X+3
- Subtract 5X from both sides 4Xy-5y-5X=5X-5X+3
- Add 5y to both sides 4Xy-5X-5y+5y=5y+3 or 4Xy-5X=5y+3
- Factor the X on the left side X(4y-5)=5y+3
- If 4y-5 does not vanish, you can isolate X by dividing both members of the equality by (4y-5).
- You get X=(5y+3)/(4y-5)=f(y)

Standard calculators can not really understand abstract notation. So 5x3/5x to the calculator is not being read as 5x (times) 3 (divided by) 5x, it is actually trying to understand x as a number. and if x isn't assigned as a number you'll get an error. SO no x's or y's or any letters. Anything with letters you have to do on your own. So 5x*3 / 5x cross out the two 5x's and you're left with 3/1 so your answer is 3.

I spoke to Overhead directly and they indicated that the HomeDepot Klick remote doesn't work with the older Overhead versions. They sold me a remote that worked for a cheaper price so I should have checked with them in the first place.

Now I'm happy after several days of frustration!

this is a simple algebraic equation in which we have to calculate the value of 'x' using simple operations

7+(9-5x)=5(2-x)

step 1(pen the brackets) 7+9-5x=10-5x

step 2(add 7 and 9) 16-5x=10-5x

now as 5x gets cancelled both the sides of the equal sign therefore no solution of this algebraic equation exist.

You can solve it with following method.

5x+3y=6 2x-4y=5

So 5x=6-3y so 2[(6-3y)/5]-4y=5

So x=(6-3y)/5 so 12-6y-20y=25

so -26y=25-12

so -26y=13

so y= -(1/2)

2x-4y=5

so 2x=5+4y

so 2x=5+4(-1/2)

so 2x=(10-4)/2

so 2x=6/4

so x =3/2

The value of x=3/2 and value of y= -1/2

Let me know if you need further assistance.

Hello,

Turn calculator ON. If you do not see several icons press [MENu].

Use arrow to select the [GRAPH] application and press [EXE].

In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.

Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.

At the position of the cursor enter 5 [X, theta,T] key under the [ALPHA]. On the screen appears 5X, complete you equation +2.

Press [EXE] to store function.

If you want to draw other functions, it is time to do so on that screen.

When done press [F6:Draw}.

If the screen does not show a lot of the function, you can use the arrow keys to pan the graph.

You can also press [SHIFT][V-Window] to set the window limits.

Hope it helps.

the exact equation is

15x^2 - 21x - 18

=3(5x^2 - 7x - 6)

=3{5x^2 -(10-3)x -6 }

=3{5x^2 - 10x + 3x -6}

=3{5x(x - 2) + 3(x-2)}

=3(x-2)(5x+3) these are the factors

Thanks
