How Do You Solve an Equation Using Addition?

'm' is a variable
Add 55 to both sides to cancel out the -55 on the left side
When adding, we have to add to both sides because of the addition property of equality
-55 plus 55 is equal to 0
37 plus 55 is equal to 92
Plug 92 in for 'm' and evaluate the expression to check our answer
92 minus 55 is equal to 37
So the left hand side equals the right hand side!

1. The addition property of equality says that if we add one thing to a side, we have to add it to the other side
2. We add 55 to both sides because it is the opposite of subtracting 55
1. Addition is the opposite of subtraction
1. -55 + 55 = 0
1. 37 plus 55 is equal to 92
1. 'm' is a variable
1. Plug 92 in for 'm' and evaluate the expression to check our answer
2. 'm' is a variable
1. 'm' is a variable
2. On the left hand side we have 92 minus 55
3. The right hand side is still 37
1. 92 minus 55 is equal to 37
2. So the left hand side equals the right hand side!
1. Since plugging 92 in for 'm' in our equation produced a true statement
2. 'm' is definitely equal to 92

Solve m-55=37 for m
