How To Solve One-Step Equations
•
•
To solve a one-step equation, do the inverse operation to both sides in order to get
the variable by itself.
Remember to check your solution
•
Example:4x=124 4=x 124=32
4 4
•
Check:4x+124
4 x 32=124
X=124
How To Solve A Two-Step
Equations
• To solve a two-step equation, first, divide your problem
by the equal sign.
• Next, circle your variable.
• Third, get rid of the number next to the variable by using
addition or subtraction.
• Finally, multiply or divide.
Example: x-7=-9 7+7=x -9+7=-2 x=-2
5 x 5=x 5
5
-2 x 5=-10
Check: x-7=-9 -10-7=-9 -2-7=-9 x=-10
