Answer:
Simplifying
5x + 11 = 31
Reorder the terms:
11 + 5x = 31
Solving
11 + 5x = 31
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11' to each side of the equation.
11 + -11 + 5x = 31 + -11
Combine like terms: 11 + -11 = 0
0 + 5x = 31 + -11
5x = 31 + -11
Combine like terms: 31 + -11 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4
