Question

Solve for x. 2(x-4)=17 a. X=1 b. X=2 c. X=12.5 d. X= 11

Answer 1

The answer is C.

Explanation: if you put 12.5 instead of x. 2(12.5-4)=17 and follow the order of operations you should get 17.

Answer 2

c. x=12.5

Explanation:

Equation Solving

Given the equation

2(x - 4) = 17

Solving for x implies doing several operations needed to have x isolated in the left part of the equation.

Dividing by 2:

x - 4 = 17/2

x - 4 = 8.5

Now we add 4:

x = 8.5 + 4

x = 12.5

Answer: c. x=12.5
