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

1 . Combine like terms
2.subtract 3 from 11 and 3
3. 3 - 3 = 0 and 11 - 3 = 8
4.turn 8 into -8 ( key change flip !! )
Check : -8 + 11 = 3

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.
