The first step is to multiply the 15 by the contents of the parentheses using the distributive property...that just means you multiply the 15 by both the terms in the parentheses:
5y + 15y - 15 = 35
combine like terms on the left:
20y - 15 = 35
add 15 to both sides:
20y = 50
divide both sides by 20:
y = 50/20 = 5/2
To check, plug back into the original equation and see if both sides come out equal:
5(5/2) + 15(5/2 - 1) =
25/2 + 15(3/2) =
25/2 + 45/2 =
70/2 = 35
Left equals right, so the solution checks out.

5y + 15y + 15 = 35
20y = 35-15
y = 20/20
y = 1

5y + 15(y + 1) = 35
5y + 15*y + 15*1 = 35
5y + 15y + 15 = 35
20y + 15 - 15 = 35 -15
20y = 20
(20y)/20 = 20/20
y = 1

y=1. Your work would look something like this:
5y+15(y+1)=35
5y+15y+15=35
20y+15=35
20y=20
y=1
Hope this helps!!

You want to distribute then add like terms.
5y +15y +15 = 35
20y + 15 -15 = 35 - 15
20y = 20
y = 1

La letra y es uno porque 5y+(15y+1)= 35 y este es 5y+15y+15=35 y 20y=35-15 y 20y=20. por lo tanto la respuesta de la pregunta es 1.
