Answer:

x = 1

Step-by-step explanation:

1. Add 3x to both sides of the problem

  • 4x + 3x - 7 = -3x + 3x
  • -3x + 3x cancels out and leaves us with zero
  • 7x - 7 = 0

2. Add 7 to both sides

  • 7x (- 7 + 7) = 0 + 7
  • -7 + 7 cancels out
  • 7x = 7

3. Divide both sides by 7

  • 7x/7 = 7/7
  • x = 1

To make sure our answer is correct we can plug in 1 to x in the problem

  • 4(1) - 7 = -3(1)
  • 4 - 7 = -3 : True

Answer:           x= 7

Step-by-step explanation:

4x-7= -3x      First add -3x on both sides

+3x      +3x

7x  -7 = 0

     +7     +7               add 7 to both sides

7x      = 7  

x = 1               divide both sides by 7
