Answer:
x = 7
Step-by-step explanation:
Reorder the terms:
3(-2 + x) = 22 + -1x
(-2 * 3 + x * 3) = 22 + -1x
(-6 + 3x) = 22 + -1x
Solving
-6 + 3x = 22 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
-6 + 3x + x = 22 + -1x + x
Combine like terms: 3x + x = 4x
-6 + 4x = 22 + -1x + x
Combine like terms: -1x + x = 0
-6 + 4x = 22 + 0
-6 + 4x = 22
Add '6' to each side of the equation.
-6 + 6 + 4x = 22 + 6
Combine like terms: -6 + 6 = 0
0 + 4x = 22 + 6
4x = 22 + 6
Combine like terms: 22 + 6 = 28
4x = 28
Divide each side by '4'.
x = 7
Simplifying
x = 7
