Explanation how to solve x+11=3 step by step

All you have to do is subtract 11 from both sides. That way, you have only "x" on the left, and 3-11 on the right, while x still keeps its original value.

x = 3-11

x = - 8

We can check it if we plug that into the original equation:

x + 11 = 3

-8 + 11 = 3

11 - 8 = 3

3 = 3, so we got the correct answer.
