L - 3 = 2(t-3) -> L = 2T-3

L - 3 = M + 27

L = 47 + W

W + 4 = (T+4)/2 -> 2W + 4 = T

In 4th equation lets replace the value of w and t with L from 1st and 3rd equation.

We get: (L-47) + 4 = (L+3)/2

Solving for L we get 61. Sub this value in the other equations and we'd get

l = 61
t = 32
m = 31
w = 14

Sum of all these = 138.


OA-A.
