1/5y + 1/8 =3/20 solve for y

y=

Step-by-step explanation:

multiply both sides

8y+5=6

move the constant to the right

8y=6-5

calculate

8y=1

divide both sides

y= or y=0.125

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
