Answer:

x = 5

Step-by-step explanation:

3(x-7)-4x = -26

First, we should multiply 3 to (x-7)

  • 3x - 21 -4x = -26

Next, we should combine like terms

  • 3x - 4x - 21 = -26
  • -x - 21 = -26

Next, we should add 21 on both sides

  • -x = -26 + 21
  • -x = -5

Cancel out the negative sign on both sides by dividing by -1

  • x=5
