Answer:

x=3

Explanation:

7-5(x+6)= -7x-17

Distribute

7 - 5x-30 = -7x-17

Combine like terms

-5x-23= -7x-17

Add 7x to each side

-5x-23+7x= -7x-17+7x

2x -23 = -17

Add 23 to each side

2x-23+23 = -17+23

2x= 6

Divide by 2

2x/2 = 6/2

x =3

Answer:

x = 3

Explanation:

7 - 5(x + 6) = -7x - 17

~Simplify left side

7 - 5x - 30 = -7x - 17

~Combine like terms

-5x - 23 = -7x - 17

~Add 23 to both sides

-5x = -7x + 6

~Add 7x to both sides

2x = 6

~Divide 2 to both sides

x = 3

Best of Luck!
