Answer:

x = 2

Explanation:

3x + 5 = 11

Let x = 1. Let's substitute the value of x into the equation to check if it's correct.

3(1) + 5 = 3 + 5

= 8

8 ≠ 11

x is not 1.

Let x = 3. Let's substitute the value of x into the equation to check if it's correct.

3(3) + 5 = 9 + 5

= 14

14 ≠ 11

x is not 3.

Let x = 2. Let's substitute the value of x into the equation to check if it's correct.

3(2) + 5 = 6 + 5

= 11

11 = 11 so you can see that the value of 2 for x satisfies the equation!

x = 2.
