Addition Property of Equality

Rule

Addition Property of Equality

The Addition Property of Equality states that adding the same number to each side of an equation yields an equivalent equation.

If a=b,a = b, then a+c=b+c.a + c = b + c.

This is one of the Properties of Equality that can be used when solving equations.

Addition Property of Equality Rules 1.svg

To isolate the variable, the subtraction of 33 can be eliminated by adding 33 to both sides of the equation, since addition is the inverse operation of subtraction.

The Addition Property of Equality also holds true if a,a, b,b, and cc are complex numbers.
