Answer:

Step-by-step explanation:

To solve this problem, first, you have to isolate x on one side of the equation.

2x-71+71=12+71 (First, add 71 from both sides.)

12+71 (Solve.)

12+71=83

2x=83

2x/2=83/2 (Then, divide by 2 from both sides.)

83/2 (Solve.)

83/2=41.5

x=83/2=41.5

So, the correct answer is x=83/2=41.5.
