Answer:

One Solution

x = -10

Step-by-step explanation:

7x + 12 = 5x − 8

  • Subtract 12 from both sides

7x + 12 - 12 = 5x - 8 + 12

  • Simplify

7x = 5x - 20

  • Subtract 5x from both sides

7x - 5x = 5x - 20 - 5x

  • Simplify

2x = -20

  • Divide both sides by 2

2x / 2 = -20 / 2

  • Simplify

x = -10
