Solving Equations-Subtraction Property of Equality
a + 12 = 18
Our goal in solving equations is to
isolate the variable.

a + 12 = 18
We always use opposite operations
when solving equations
The opposite of adding is subtracting.

Solving Equations-Addition
a + 12 = 18a + 12 – 12 = 18 -12
Solving Equations-Subtraction Property of Equality
Balanced the equation by subtracting 12 from
both sides of the equal sign.
