Final answer:
To solve the equation h=ab+r for a, subtract r from both sides and divide by b.
Step-by-step explanation:
To solve the equation h=ab+r for a, we need to isolate a on one side of the equation.
Step 1: Subtract r from both sides to isolate the term with a: h - r = ab
Step 2: Divide both sides by b to solve for a: (h - r) / b = a
So, the solution for a is (h - r) / b.
