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
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
