Subtraction Property of Equality

The Subtraction Property of Equality states that when the same quantity is subtracted from both sides of an equation, the two sides remain equal. Mathematically, for any numbers aa, bb, and cc:

If a=ba = b, then ac=bca - c = b - c

This property is a fundamental mathematical tool for solving equations. By applying it, one can systematically remove unwanted terms from one side of an equation by subtracting them from both sides, which helps to isolate the unknown variable by itself.
