Question

how to do equation with example

Answer 1

ok if you cant understanding i can explain in easy language

Answer 2

First, write down the expression:
say,

3a + 1 = 7.

Then, undo the + 1 by subtracting 1. Remember, you need to do it to BOTH sides!

3a + 1 - 1 = 7 - 1

so 3a = 6

Undo the multiply by 3 by dividing by 3, again on both sides:

3a ÷ 3 = 6 ÷ 3.

a=2
