You have the following equation:
[tex]11+\frac{1}{3}t=1+\frac{1}{4}t[/tex]In order to solve the previous equation for t, you proceed as follow:
11+(1/3)t = 1+(1/4)t multiply both sides by 12 (to eliminate denominators)
132 + 4t = 12 + 3t subtract 3t both sides, and subtract 132 both sides
4t - 3t = 12 - 132 simplify
t = -120
Hence, the solution to the given equation is t = -120
