You can put this solution on YOUR website!
5Y + 15(Y +1) = 35
5Y + 15Y + 15 = 35 [multiply using the distributive property]
20y+15=35 [combine like-terms]
20y+15-15=35-15
20y=20
20y/20=20/20
y=1
.
check by plugging (y=1) back into the original equation.
5Y + 15(Y +1) = 35
5(1) + 15(1 +1) = 35
5 + 15(2) = 35
5+30=35
35=35 [checks out]
