For this Question use the substitution method.
5x+2y = $48 ------First Equation.
3x+2y = $32 ------ Second Equation
x= 48-2y/ 5 ( 48-2y divided by 5)
Put the value of x in the second equation.
3(48-2y/5)+2y = $32
(144-6y/5) + 2y = $32
Take L.C.M
144-6y+10y/5 = $32
144+4y = 32*5
144+4y = 160
4y = 160-144
4y = 16
y = 4
Now put the value of y in any equation.
5x+2(4) = $48
5x+8 = $48
5x = 48-8
5x = 40
x = 8

First you add what's in the parenthesis first then add that to 3.25 and there's your answer
Answer:
you can make 3 rectangles with an area of 12in
The area would be (x+3) (4x-1) which is 4x^2 +11x -3. The perimeter is 2(x+3) plus 2(4x-1) which is 2x +6 plus 8x-2 which is 10x +4. If x=7 then the perimeter is 74 ft.
