1) Find the unknown m.
2)Bring over the denominators to the other sides.
7(m+3) = -(m-5)4
7m + 21 = -4m +20
3) bring all the value m to one side and the whole numbers to the other.
11m = -1
m = -1/11
4) sub numbers in for m
7(m+3) = 4(m-5)
5) both sides should have the same answer.
i got -224/11 for both.
answer: m = -1/11
