7+0.6(1-y)=1.6y-5(y-0.2)

Question

7+0.6(1-y)=1.6y-5(y-0.2)
7+0.6-0.6y=1.6y-5y+1
10{7+0.6-0.6y}=10{1.6y-5y+1}
70+6-6y=16y-50y+10
76-6y=-34y+10
76+28y=10
28y=-66
y=-66/28
y=-33/14

This is another question on the quiz and that is how i worked it out and come to my solution but the answers on the quiz are as followed

y=-13/4
y=0
y=-9/2
y=-43/14

and once submitted It will say the correct answer is y=0
with the only instructions still being to solve for y
Am I crazy or did I miss something?

Answer 1

Justin, you did not distribute the -5 in your first step. - 5(-1) = 5 and not 1.

 

Simple error!
