Question

Solve the equation. 78 = -2 (m+3) + m

Answer 1

ok distribute the -2 to the m + 3

Answer 2

first distribute the -2 so 78 = -2m + 6 + m. then combine like terms. so 78 = m + 6. then isolate the variableby subtracting 6 from both sides, thus m = 72

Answer 3

wouldnt it be -72?

Answer 4

you would get 78 = -2m - 6 + m

Answer 5

-2m + m = -m

Answer 6

-39 = 2m + 3

-42 = 2m

m = -21

Answer 7

A. –28

B. –42

C. –72

D. –84

Answer 8

78 = -m - 6

Answer 9

72=-m
