Answer:
Solution : x = 2
y = 3
Step-by-step explanation:
x+y = 2y-x+1=5
x + y = 5 --------> equ 1
2y - x +1 = 5
2y - x = 5 - 1
2y - x = 4
-x + 2y = 4--------> equ 2
add equ 1 & equ 2
3y =9
y = 9/3 = 3
Put y = 3 in equ 1
x + 3 = 5
x = 5 - 3 = 2
Solution : x = 2
y = 3

Answer:
The area of the rectangular coral = 2,976 ft²
Step-by-step explanation:
Bryce has 220 ft of fencing to fence a rectangular coral.
Let the dimensions of the corral be x ft. × y ft.
One side of the coral is 48 ft. long
A rectangle has 4 sides, with each of the two opposite sides with the same dimension. Hence, the perimeter of the rectangular coral = 2(x + y) = 2x + 2y.
Total length of material for fencing = 220 ft.
Hence the perimeter of the reef = 220 ft.
2x + 2y = 220
And one length of the rectangular coral = x = 48 ft.
We can solve for the remaining dimension of the rectangular coral this way.
2(48) + 2y = 220
2y = 220 - 96 = 124
y = (124/2) = 62 ft.
Hence, the area of the rectangular coral = xy = 48 × 62 = 2,976 ft²
Hope this Helps!!!
