Question

What is the solution to the equation -5 =8m +12 /4

Answer 1

`-5 =8m + (12)/(4) \\ \\ -5 = 8m + 3 \\ \\ -5 - 3 = 8m \\ \\ -8 = 8m \\ \\ - (8)/(8) =m \\ \\ -1 = m \\ \\ m = -1 \\ \\ Answer: \fbox {m = -1}`

Answer 2

m = -1

-5 = 8m + 12/4
-5 - 12/4 = 8m
4(-5) - (12/4) = 4(8m)

*to remove the denominator, multiply each figure by 4.

-20 -12 = 32m
-32 = 32m
-32/32 = 32m/32
-1 = m

m = -1

To check:

-5 = 8m + 12/4
-5 = 8(-1) + 3
-5 = -8 + 3
-5 = -5
