2. Solving a Single-Step Equation by Subtraction
Get rid of any number surrounding the variable.
Step 2:
Repeat the same process on the other side of the equal sign.
Step 2:
To balance the equation, repeat the same process on the other side of the equal sign.
𝑥+30=4
Step 1:
To solve for x, we need to get x by itself. Thus, we need to get rid of 30.
To do so, we must subtract 30
to 30.
−30 0
−30
−26
𝑥=−26
Step 2:
Simplifying our equation results in x = -26, and that is our answer.
