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.

Identify the property shown. −1.4+(−2.6+3.8)=(−1.4+(−2.6))+3.8

Dimas [21]

<span>This property is called associativity. It shows that it doesn't matter whether you perform the sum on the first two numbers and then the third, or on the second two and then the first, because you will get the same answer either way. That is because addition is associative.</span>
