1. The problem is to solve an algebraic equation or expression without using subtraction. 2. Instead of subtraction, we can rewrite expressions using addition and multiplication by negative numbers or distribution. 3. For example, if the equation was $x - 3 = 0$, we rewrite subtraction as addition: $x + (-3) = 0$. 4. Then solve by isolating $x$, adding 3 to both sides algebraically: $x = 3$. 5. This method avoids explicit subtraction by using additive inverses. 6. Hence, the solution to such problems is equivalent, just rewritten without subtraction.
