Question

Which of the following equations is equivalent to 2(a + 6) – 3(a – 5) = 18?

A: 5a + 27 = 18
B: 5a - 3 = 18
C: -a + 27 = 18
D: -a + - 3 = 18

Answer 1

c

Explanation:

Answer 2

answer: c

use distributive property:
2(a+6)-3(a-5)+15=18
2a+12-3a+15=18

combine like terms:
2a+12-3a+15=18
-a+27=18
