Answer:
y=7
x=5
Step-by-step explanation:
x-y=-2
+y +y
x=-2+y
then substitute -2+y into the x in the other equation
so:
2(-2+y) + 4y = 38
-4+ 2y +4y = 38
-4+6y= 38
+4 +4
6y=42
divide both sides by 6
y=7
to get X:
x-y=-2
x-(7)=-2
+7 +7
x=5
ok consider a rectangle with two sets of equal sides
call one side of a set x
and one side of the other set y
we know she has 140 meters of rope so perimeter of the rectangle = 140
so 2x + 2y= 140
hence X = (140- 2y)/2
the dimensions have to satisfy the above equation
