8). y=3x+23

Step-by-step explanation:

1).

3x-y=5

Subtract 3x from both sides

-y=5-3x

Multiply both sides by - 1

y = - 5+3x

2).

y+7 = - 2 (x+3)

y+7 = - 2x-6

Subtract 7 from both sides

y = - 2x-13

3).

y = - 10-6 (x-2)

y = - 10-6x+12

y = - 6x+2

4).

3x=12-3y

Add 3y to both sides

3x+3y=12

Subtract 3x from both sides

3y=12-3x

Divide both sides by 3

y = - x+4

5).

-4x-7y=0

Add 4x to both sides

-7y = - 4x+0

Multiply both sides by - 1

7y = 4x

Divide both sides by 7

y≈ 0.57x

6).

4x-2y=18

Subtract 4x from both sides

-2y = - 4x+18

Multiply both sides by - 1

2y=4x-18

Divide both sides by 2

y=2x-9

7).

y = 5-

Equation is incomplete.

8).

y-2=3 (x+7)

y-2=3x+21

Add 2 to both sides

y=3x+23
