Algebra 1: Common Core (15th Edition)

We first subtract by 1/4t on both sides to get that $1/12t+2=1$. We need to get the t alone. Thus, we cancel out the addition by subtracting 2 on both sides, giving us: $1/12t=-1$. We then isolate t by multiplying by the reciprocal of 1/12, 12/1, to obtain that $t=-12$.
