Answer:
Simplifying
3x + -15 = 21
Reorder the terms:
-15 + 3x = 21
Solving
-15 + 3x = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 3x = 21 + 15
Combine like terms: -15 + 15 = 0
0 + 3x = 21 + 15
3x = 21 + 15
Combine like terms: 21 + 15 = 36
3x = 36
Divide each side by '3'.
x = 12
Simplifying
x = 12
