4y - 3 = y + 6    |add 3 to both sides

4y = y + 9      |subtract y from both sides

3y = 9    |divide both sides by 3

y = 3

check:

L = 4 · 3 - 3 = 12 - 3 = 9
R = 3 + 6 = 9

L = R

If your are looking for y then y = 3

4y-3=y+6
Get your y's to one side then subtract from the right.
3y-3=6
Then move the minus three to the right.
3y=9
Then simply divide by three.
