Calculator Output

Simplifying
3 + 4x + 10 = 5x

Reorder the terms:
3 + 10 + 4x = 5x

Combine like terms: 3 + 10 = 13
13 + 4x = 5x

Solving
13 + 4x = 5x

Solving for variable 'x'.

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

Add '-5x' to each side of the equation.
13 + 4x + -5x = 5x + -5x

Combine like terms: 4x + -5x = -1x
13 + -1x = 5x + -5x

Combine like terms: 5x + -5x = 0
13 + -1x = 0

Add '-13' to each side of the equation.
13 + -13 + -1x = 0 + -13

Combine like terms: 13 + -13 = 0
0 + -1x = 0 + -13
-1x = 0 + -13

Combine like terms: 0 + -13 = -13
-1x = -13

Divide each side by '-1'.
x = 13

Simplifying
x = 13
