Given an equation, subtracting the same number from each side of the equation yields an equivalent equation.
The Subtraction Property of Equality also holds true if a, b, and c are complex numbers. This property is one of the Properties of Equality that can be used when solving equations. x+2x+2−2x=7=7−2=5 To isolate the variable, the addition of 2 can be eliminated by subtracting 2 from both sides of the equation, since subtraction is the inverse operation of addition.
