Simplifying
5x + 12 = 58
Reorder the terms:
12 + 5x = 58
Solving
12 + 5x = 58
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 5x = 58 + -12
Combine like terms: 12 + -12 = 0
0 + 5x = 58 + -12
5x = 58 + -12
Combine like terms: 58 + -12 = 46
5x = 46
Divide each side by '5'.
x = 9.2
Simplifying
x = 9.2
