PLEASE HELP

1.Solve the following system of equations using substitution.

y = 2x-2

-4x-y = 26

Solve for x: Solve for y:

2.Solve the following system of equations using elimination.

5x+y=24

-5x-4y=-56

Solve for y: Solve for x:

3.For each systems of equations below, choose the best method for solving

and solve. Show your work.

a. 3x+y=24

-x-y=-10

4.y=-x-6

x+3y=-18

5.y=-2x+17

y=8-x

6.y=x-7

y=x+7

7.y+2x=2

y=-4x+10

8. x+2y=-4

-4x-3y=16
