$y = 3/8$

Re-arrange the terms to have all the y terms on the left and the numbers on the right.
Sometimes things can be kept really simple..

$y+ 1/2 = 1-y/3$

$y +y/3 = 1-1/2" ( y + one third of y = 4/3 y)"$

$4/3 y = 1/2$

$3/4 xx 4/3 y = 1/2 xx3/4$

$y = 3/8$

How do you solve y+1/2 = 1-y/3 y+1/2 = 1-y/3?
