Answer:
Step-by-step explanation:
Simplifying
3x + -1 = 71
Reorder the terms:
-1 + 3x = 71
Solving
-1 + 3x = 71
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + 1 + 3x = 71 + 1
Combine like terms: -1 + 1 = 0
0 + 3x = 71 + 1
3x = 71 + 1
Combine like terms: 71 + 1 = 72
3x = 72
Divide each side by '3'.
x = 24
Simplifying
x = 24
