Answer:
length: y = 5
width: x = 4
Step-by-step explanation:
The perimeter is twice the sum of length and width:
P = 2(L+W)
18 = 2(y +x) . . . . . using the given values
The difference in dimensions can be expressed as ...
y -x = 1
When the above two equations are graphed, we see the solution is ...
(x, y) = (4, 5)
