You can simplify this by including the 1 and also the 4 together, and the 3y and also the 2y together. This leaves you v 80=5y + 5. If you climate subtract the 5 end to the other side you get 75=5y. Divide both political parties by 5 and you gain y=15.


You are watching: Solve this equation: 80 = 3y + 2y + 4 + 1.

using a graphing tool

Plot the rectangle

see the attached number to better understand the problem

we understand that

The x-coordinate of S should be same to the x-coordinate of suggest P

The y-coordinate of S need to be same to the y-coordinate of allude R

because SP must be parallel come QR

therefore
