Explanation:

Simplifying

5x = 3x + 8

Reorder the terms:

5x = 8 + 3x

Solving

5x = 8 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

5x + -3x = 8 + 3x + -3x

Combine like terms: 5x + -3x = 2x

2x = 8 + 3x + -3x

Combine like terms: 3x + -3x = 0

2x = 8 + 0

2x = 8

Divide each side by '2'.

x = 4

Simplifying

x = 4
