What is the solution to this system of linear equations?
x-3y = -2
x + 3y = 16
(7,3)
(3,7)
(-2, -3)
(-3,-2)

(7, 3)

Step-by-step explanation:

get rid of the y by adding:

 x=-2

+x=16

then add the equalities:

2x=14

divide by 2:

x=7

then subsitute the x in to find y!

7+3y=16

3y=16-7

3y=9

y=3

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
