Question

Solve the problem and find the value of the variable:

2x−5=11

a) x=3
b) x=8
c) x=−3
d) x=−8

Answer 1

To solve the equation 2x - 5 = 11, add 5 to both sides to get 2x = 16, and then divide by 2 to find x = 8.

Step-by-step explanation:

To solve the equation 2x - 5 = 11, follow these steps:

1. Add 5 to both sides of the equation to isolate the term with the variable on one side. This gives us 2x = 16.
2. Divide both sides of the equation by 2 to solve for x. This yields x = 8.

Therefore, the value of the variable x is 8, which corresponds to option b).
