You will need to work 120 hours in order to earn 300$ to get the ps4.
<span>t/(t-8)=(t+8)/30
(t+8)(t-8) = 30t
t^2 - 8^2 = 30t
</span>t^2 - 30t - 64 = 0
<span>(t-32)(t+2) = 0
so t = 32 and t = -2
answer: 2 solutions </span>t = 32 and t = -2<span>
</span>
-3=7x-10. -7x=3-10. X=1. You can check the answer by plugging in the numbers.
