My solution and answers are wrong.. they are as follows. I have done it in so many ways and come up with so many different answers, my head is fried. I will do it side by side with the rules in the textbook next (i'm certain i applied the PEMDAS concepts). In the mean time.. and yeah not done the efficient way, did it step by step..

0.25(q-8) = 0.1(q+7)

1/4(q-8) = 1/10(q+7)

1/4q-1/10q-2 = 0.7

10/40q-4/40q-2 =0.7

6/40q-2+2=0.7 +2

6/40q = 2.7

40(6/40q) = 40(2.7)

6q = 14.81

q = 2.45????
