How do you write and solve equation with an unknown number?

1 answer:

8 0

You have to isolate the variable using inverse operations in order to get it alone. Example: x+3=5
Subtract 3 on both sides since you are adding 3, and subtraction is the opposite of addition.
x=2 is your answer. If you check and plug it in, you will see that it is a correct equation.
