Question

The perimeter of the rectangle is 24 and the perimeter of the triangle is 23. The equations for the triangle is x+1, x+y, and y+6. The equations for the rectangle is x and 3y. Write an equations to that represents the perimeter of the triangle. Write an equation in standard form the represents the perimeter of the rectangle. Write a system of linear equations to represent the problem. The solve the system of linear equations to find x and y.

Answer 1

if those equations represent the side lengths

x+1+x+y+y+6 = 23
2x+2(3)y = 24

x+y=8
x+3y=12

x=8-y
x=12-3y

8-y=12-3y
2y=4
y=2
x=6

Answer 2

where do you get the 3 from in the first and second equations?

Answer 3

never mind i see
