3y=15x-12

How to solve for y?

Have to isolate the variable. divide everything by 3 so the problem would now be y=5x-4

First you divide both sides by three.

3y=15x-12
/3    /3  /3

y=5x-4

y cannot be solved in this equation, but you should get y by it self.

i believe your answer is b.

good luck!

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
