4 - t = 3(t - 1) - 5
= 4 - t = (3t - 3) - 5
= 4 - t = 3t - 8
Add 8 to both sides:
12 - t = 3t
Add t on both sides:
12 = 4t
Divide both sides by 4:
t = 3
Hope I helped :)
EDIT: Yeah I see where I went wrong - answer is 3
Answer:
−40+2n=−4n+8
−40+2n+40=−4n+8+40
2n=−4n+48
2n+4n=−4n+48+4n
6n=48
answer: n=8
