7-y+5y=9
7+4y=9 Add 5y and -y
4y=2 Minus 7 from both sides
y=1/2 Divide 4 by both sides and u get 2/4 which is 1/2

7-y+5y=9
well first you have to combine all the like terms so -y+5y=4y
so then it will turn into 7+4y=9
you then subtract 7 from both sidesz leaving 4y=2
so then to get y by it self you have to divide both sides by 4 and will get y=2/4 then simplify and you will get y=1/2 so the answer is y=1/2

7 - y + 5y = 9
-y + 5y = 9-7
4y = 2
y = 2/4 = 1/2

It's been a while but, here's a try:
7-y+5y=9
5y-y+7=9
4y+7=9
4y+7-7=9-7
4y=2
4y/4=2/4
y=1/2
