Okay. So first you subtract 2x from each side. That will give you 4y= -2x+18 (you want to get y by itself). Then you divide both sides by 4. It should equal> y= 1/2x +9/2
remember you can do ANYTHING to an equation as long as you do it to both sides

isolate the y and then divide by the coefient
the basic way to simplify it is if you did
ax+by=c
y=[tex] \frac{-a}{b}x+ \frac{c}{b} [/tex]

but memorization is no fun so



4y+2x=18
minus 2x both sides
4y=-2x+18
divide both sides by 4
[tex]y= \frac{-1}{2}x+ \frac{9}{2} [/tex]
