here's how you solve:
step 1 - distribute:
5*1/8*y + 64*1/8 = 1/4*20+1/4*2*y
5/8y + 8 = 5 + 1/2y
step 2 - combine like terms:
5/8y - 1/2y = 5 - 8
5/8y - 4/8y = -3
1/8y = -3
step 3 - solve for y:
1/8 * 8 * y = -3 * 8
y = -24

8[1/8(5y+64)= 1/4(20+2y)] =
5y + 64 = 2(20 + 2y) =
5y + 64 = 40 + 4y =
y = -24

1/8(5y+64)=1/4(20+2y) <------distribute the fractions
5/8y + 8 =5 +1/2y <---minus 1/2 and 8 to both sides
1/8y = -3 <-----divide both sides by 1/8
y = -24

1/8 (5y+64)=1/4(20+2y)
take the whole thing X 8
5y+64=40+4y
-4y from each side
y+64=40
-64 from each side
y=-24

y=-24
multiply everything by 8
then solve
5y+64+2(20+2y)
5y+40+4y
y=-24

Y=-24
you basically double the side that is *1/4, then cross stuff off from both sides, then you will get 0=24+y, so of course the answer is -24
