Question

Solve for x: 3x + 2 = 11
a) x = 1
b) x = 3
c) x = 5
d) x = 6

Answer 1

To solve for x in the equation 3x + 2 = 11, subtract 2 from both sides to get 3x = 9, then divide by 3 to find x = 3, making option b) the correct answer.

Step-by-step explanation:

To solve for x in the equation 3x + 2 = 11, we must perform two logical steps:

1. First, we need to isolate the variable x on one side of the equation. We do this by subtracting 2 from both sides of the equation to get 3x = 9.
2. Then, we divide both sides of the equation by 3 to find x. Doing this gives us x = 3.

Therefore, the solution for x in the equation given is x = 3, which corresponds to option b).
