Question

Tommy thinks the two expressions below are equivalent

-3 (6a - 5) + 4a and
22a + 15
A) Is he correct?
B) Explain why or why not?

Answer 1

no, they are not equivalent expressions

Explanation:

simplify: -3(6a - 5) + 4a = -3(6a) + (-3)(-5) + 4a = -18a + 15 + 4a = -14a + 15

-14a + 15 ≠ 22a + 15
