Calculator can't do it, its Transposition, you don't say what it equals....

I don't believe the brackets are needed, I've put them in to seperate the parts as you have written them.

((2x+3y-6z)+(5x-3y)) - (8x-y+5z) =

(7x-6z) - (8x-y+5z) =

-x-y-11z =

5x (-3x) = 2x -3x - -3x = 0

The equation then becomes 2x=10 2x/2 = x and 10/2 =5

then x=5. does it work 5x5=10+3*5 YES

Let the two numbers be X and Y:

X + 3Y = 5

2X + Y = 8

Rewrite the second equation to Y = 8 - 2X and substitute in first equation:

X + 3(8-2X) = 5

X + 24 - 6X = 5

-5X + 24 = 5

-5X = 5 - 24

-5X = -19

X = 19/5 =**3.8**

Y = 8 - 2(3.8) = 8 - 7.6 =**0.4**

Check: 3.8 + 3(0.4) = 3.8 + 1.2 = 5

2(3.8) + .4 = 7.6 + 0.4 = 8

X + 3Y = 5

2X + Y = 8

Rewrite the second equation to Y = 8 - 2X and substitute in first equation:

X + 3(8-2X) = 5

X + 24 - 6X = 5

-5X + 24 = 5

-5X = 5 - 24

-5X = -19

X = 19/5 =

Y = 8 - 2(3.8) = 8 - 7.6 =

2(3.8) + .4 = 7.6 + 0.4 = 8

Your calculator cannot, natively, perform 3D graphing.

To find the solution, first find the value of y for each equation.

Then substitue one equation into the other so that you only the x variable left.

Then just solve for x.

Once you have a value for x, then you can easily solve for y.

So for the first equation:

3y - 6x = -3

3y = 6x - 3

**y = 2x - 1**

Now for the second equation:

2y + 8x = 10

2y = -8x + 10

**y = -4x + 5**

Since both equations equal y, they also equal each other, therefore:

2x - 1 = -4x + 5

Now just solve for x:

2x + 4x = 5 + 1

6x = 6

**x=1**

Now substitute x=1 into either original equation:

y = 2x - 1

y = 2 (1) - 1

y = 2 - 1

**y = 1**

Therefore the solution is x=1 and y=1

Good luck, I hope that helps.

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

5x -2x +4 = 6 +6x +6 (use the distributive property)

3x + 4 = 6x + 12 (collect terms)

4 = 3x + 12 (subtract 3x from both sides to get all x on one side)

-8 = 3x (subtract 12 from both sides to get only x on one side)

-8/3 = x (divide both sides by 3 to get x by itself)

Check

5(-8/3) -2((-8/3)-2) = 6 - 2(-3(-8/3)-3)

-40/3 -2(-8/3-6/3) = 6 - 2(8-3)

-40/3 -2(-14/3) = 6 -2(5)

-40/3 + 28/3 = 6 - 10

-12/3 = -4 (yes)

5x -2x +4 = 6 +6x +6 (use the distributive property)

3x + 4 = 6x + 12 (collect terms)

4 = 3x + 12 (subtract 3x from both sides to get all x on one side)

-8 = 3x (subtract 12 from both sides to get only x on one side)

-8/3 = x (divide both sides by 3 to get x by itself)

Check

5(-8/3) -2((-8/3)-2) = 6 - 2(-3(-8/3)-3)

-40/3 -2(-8/3-6/3) = 6 - 2(8-3)

-40/3 -2(-14/3) = 6 -2(5)

-40/3 + 28/3 = 6 - 10

-12/3 = -4 (yes)

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.
