Step-by-step explanation:
The width of the mattress is 7.
Give that
- The area of the mattress is 56 square feet.
- The length is 8.
- And, the width of the bed is x + 4.
Now as we know that
Area of the rectangle = Length × width
56 square feet = 8 × (x + 4)
56 = 8x + 32
56 - 32 = 8x
x = 3
So, the width is
= 3 + 4
= 7
Therefore we can conclude that the the width of the mattress is 7.

Hello,
7x-4y=-8 (1)
y=3/4x-3==>3x-4y=12 (2)
(1)-(2)==>4x=-20 ==>x=-5
if x=-5 then (1)==>4y=-35+8==>y=-6.75
