campbell_st · Answer

if the question is 

$$\frac{15t}{5} = \frac{2t + 3}{6}$$

cross multiply 

90t = 10t + 15

then solve for t

I got 7.5t which isn't a choice

campbell_st · Answer

wow.... I can understand why 7.5t isn't a choice... 

   90t = 10t + 15                   subtract 10t from both sides of the equation
 -10t    -10t
-------------------
  80t = 15

now solve for t
