Question 69053


{{{a+3/8 +a/5=2}}} LCM is 40;  multiply each term by 40

{{{40*a+40*(3/8)+40(a/5)=40*2}}}  simplify

{{{40a+15+8a=80}}}  subtract 15 from both sides

{{{40a+8a+15-15=80-15}}}  collect like terms

{{{48a=65}}}  divide both sides by 48
{{{a=65/48}}} or

{{{a=1.3542}}}-------------------------------------ans

Substitute the value of a into the original equation:
{{{1.3542+0.375+0.27084=2}}}

{{{2=2}}}
