Question 600801
When fractions are involved you must always put the parenthesis at the right place. Your problem can be interpreted in two ways


{{{5+(a/6)=4}}}

Multiply the equation by 6 to eliminate the denominator

30+a = 24

-30
a=-30+24
a= -6



{{{(5+a)/6=4}}}

Multiply by 6

5+a= 24
-5
a= 24-5
a= 19
