omg i totally hate algebra..

but im learning this too (:

first you take 1/8(5y)+1/8(64)=1/4(20)+1/4(2y)

then you reduce. .625y+8= 5+.5y ((and yes I did have to use a calculator. lol))

take away .5y from .625y = .125y

.125y+8=5

-8+-8

.125y=-3

divide .125y/.125 = -3/.125

y = -24

good luck with algebra (:

(5y+64)/8=(20+2y)/4 now cross multiply

4(5y+64)=8(20+2y)

20y+256=160+16y now put like terms together

20y-16y=160-256

4y=-96 divide both sides by 4

y=-24

1/8(5y+64)=1/4(20+2y)

1/2(5y+64)=20+2y

1/2(44)=-3y

22=-3y

y=(-22/3) or -7.333333
