Question

how do I solve x+2/3=5/6

Answer 1

You would subtract 2/3 from 5/6 and that should give you 1/6
x=1/6

Answer 2

assuming that is x+(2/3)=5/6 and not $\frac{x+2}{3}$=5/6

minus 2/3 both sides
$x= \frac{5}{6} - \frac{2}{3}$
2/3 times 2/2=4/6
$x= \frac{5}{6} - \frac{4}{6}$
$x= \frac{5-4}{6}$
$x= \frac{1}{6}$
