1) 2 (x - 5) + 7 = x + 8

what is x

2) 5 (x - 1) - 6x = - 11x

what is x

x = 11

1/2 = x

Step-by-step explanation:

1) 2 (x - 5) + 7 = x + 8

Distribute

2x-10+7 = x+8

Combine like terms

2x - 3 = x+8

Subtract x from each side

2x-x-3 = x+8-8

x - 3 = 8

Add 3 to each side

x-3+3 = 8+3

x = 11

2) 5 (x - 1) - 6x = - 11x

Distribute

5x-5-6x = - 11x

Combine like terms

-x-5 = - 11

Add x to each side

-x+x - 5 = - 11x + x

-5 = - 10x

Divide each side by - 10

-5/-10 = - 10x/-10

1/2 = x
