Step-by-step explanation:

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
