Remember
-an opposite operation is an operation that "undoes" another operation.
-subtraction and adding are opposites
-division and multiplication are opposites
-whatever you do one side you must do the same to the other side to maintain balance
1st step- isolate the variable/get the letter by itself
2nd step- apply opposite operation
3rd step- check the answer, substitute the answer for the letter of the original equation
A+5=7
-5 -5
A=2
Check your answer:
A+5=7
2+5=7
7=7
To extend our knowledge, we had equations to solve:
a) b-3=5
- +3 +3
- b=8
Check your answer:
b-3=5
8-3=5
8=8
b) c÷3=7
- x3 x3
- c=21
Check your answer:
c÷3=7
21÷3=7
21=21
c) 4d=16
- ÷4 ÷4
- d=4
Check your answer:
4d=16
4(4)=16
16=16
