5/8m-3/8=1/2m+7/8 how do you solve this. variables on both sides. step by step !

Combine like terms:  (5/8)m - (1/2)m = 7/8 + 3/8 = 10/8

                                        (1/8)m = 10/8

Now mult both sides by 8 to remove 8 from the denominators:

                                             m = 10

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

i think this could be a possible answer (1 / 84) -1

good luck! : d
