a%2B3%2F8+%2Ba%2F5=2 LCM is 40; multiply each term by 40
40%2Aa%2B40%2A%283%2F8%29%2B40%28a%2F5%29=40%2A2 simplify
40a%2B15%2B8a=80 subtract 15 from both sides
40a%2B8a%2B15-15=80-15 collect like terms
48a=65 divide both sides by 48
a=65%2F48 or
a=1.3542-------------------------------------ans

Substitute the value of a into the original equation:
1.3542%2B0.375%2B0.27084=2
2=2
