3[5-3(4-t)]-2    =8-3(5t-4)
3(5-12+3t)-2   =8-15t+12
3(·7+3t)-2      =20-15t
(9t-21) - 2      =20-15t
9t-21-2          = 20- 15t
9t-23             = 20-15t
24t                = 43

t =  \frac{43}{24}
t = 1.79

3(5-12+3t)-2=8-15t+12
15-36+9t-2=8-15t+12
9t+15t=-15+36+2+8+12
24t=43
----------       THE ANSWER IS t=43/24 or 1 19/24
