t would be -5.
How I solved this:
= 3_t_ + 7 = -8
= 3_t =_ -8 - 7
= 3_t_ = -15
= t = -15/3
= t = -5
3t+11 = 29 3t = 29-11 3t = 18 t = 6
4+3t = 22 3t = 22-4 t = (22-4)/3 t = 6
-12t+4
S = 3 st + 3t = 6 st = 6 - 3t s = (6 - 3t)/t = 6/t - 3
In 2t+8 19
3t+11 = 29 3t = 29-11 3t = 18 t = 6
s = 7, t = -3
4+3t = 22 3t = 22-4 t = (22-4)/3 t = 6
-12t+4
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
S = 3 st + 3t = 6 st = 6 - 3t s = (6 - 3t)/t = 6/t - 3
In 2t+8 19
t = -11/10
8
15t+25 = 5(3t+5)
Yes and t = 1 in both equations
4t-1 = t+2 3t -1 = 2 3t = 3 t = 1
