Question

5(x-4) = 3x +4 What is the solution to this equation?

Answer 1

5x+4=3x−4

Move all terms containing x to the left side of the equation.

2x+4=−4

Move all terms not containing x to the right side of the equation.

2x=−8

Divide each term by 2 and simplify.

x=-4

Answer 2

x = 12

Explanation:

1. Distribute:

5(x-4) = 5x - 20

2. Set equal to each other:

5x - 20 = 3x + 4

3. Simplify both sides:

5x - 20 = 3x + 4

-3x+20 = -3x+20

2x = 24

4. Solve:

2x/2 = 24/2

x = 12
