Explanation:
"one way is to eliminate the fractions by multiplying"
"the terms by the lowest common multiple of 10 and 15"
"the lowest common multiple is "30
cancel(30)^3xxt/cancel(10)^1+cancel(30)^2xxt/cancel(15)^1=30
rArr3t+2t=30
rArr5t=30
"divide both sides by 5"
(cancel(5) t)/cancel(5)=30/5
rArrt=6" is the solution"
