t-(2t+5)-5(1-2t)=2(3+4t)-3(t-4)

Question

I really don't get this question so if someone would help me I would be very happy

Answer 1

t - (2t+5) -5(1-2t) = 2(3+4t) - 3(t-4)

expand

t-2t-5 -5 +10t = 6 +8t -3t + 12

combine like terms

9t - 10 = 5t + 18

4t = 28

divide both sides by 4

t = 28/4 = 7

t = 7
