Answer:
(3,4)
Step-by-step explanation:
first you're going to solve the equation -2x
your equation should now be: 
next you're going to substitute the given value of -2x into the equation 
so your equation should now be: 
next you're going to solve the equation for y
equation should now be: y=4
than you're going to substitute the given value of y into the equation
×
then you're going to solve the equation for x
your equation should now be: x=3
then the possible solution of the system is the order pair: (x,y)=(3,4)
Let the length of the patio is x and width is 3/4x
So according to the equation x.3/4x = 432
x^2. 3/4 =432
x^2 =432 times 4/3
x^2 =1728/3 =576
x= 24
The length is 24 ft
