Raul wants to solve the equation x- 5 = 7. He begins by subtracting 5 from both sides. Is Raul's method correct? Explain.
No. Raul should add 5 to both sides instead.
-5 and 5 are opposites, so they will cancel each other out and leave 0. Then, the equation will read
x - 5 + 5 = 7 + 5
x = 7 + 5
x = 12
