X=-2

2(x - 4) + 5x = -22

Distribute first.

2x - 8 + 5x = -22

Combine the x's.

7x - 8 = -22

Add eight to both sides.

7x = -14

Divide both sides by seven

x = -2

That's the first problem. Second one is incomplete....

a) 2(x - 4) + 5x = - 22

2x - 8 + 5x = - 22

7x - 8 = - 22

7x = - 14

x = - 2.

a) 2(x-4) + 5x = -22

2x-8+5x = -22

7x+8= -22

7x = -30

x = -30/7
