4 (3x + 5) - 3 = 9x - 7 what is x?

x = - 8

Step-by-step explanation:

4 (3x + 5) - 3 = 9x - 7

Distribute

12x + 20 - 3 = 9x - 7

Combine like terms

12x+17 = 9x-7

Subtract 9x from each side

12x-9x + 17 = 9x-9x-7

3x + 17 = - 7

Subtract 17 from each side

3x+17-17 = - 7-17

3x = - 24

Divide each side by 3

3x/3 = - 24/3

x = - 8

Answer: x = - 8

Step-by-step explanation:

4 (3x + 5) - 3 = 9x - 7

12x + 20 - 3 = 9x - 7

12x + 17 = 9x - 7

subtract 9x from both sides

12x + 17 - 9x = - 7

3x + 17 = - 7

subtract 17 from both sides

3x = - 7-17

3x = - 24

divide both sides by 3

x = - 24/3

simplify

x = - 8
