Question

4x - 7 = -3x What is the answer?

Answer 1

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

Answer 2

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
