Answer:
Width = 12
Length = 58
Step-by-step explanation:
Width = x
Length = 4x + 10
Perimeter = 140
2 * ( length + width ) = 140
2 * (4x +10 + x) = 140
5x + 10 = 140/2 = 70
5x = 70- 10
5x = 60
x = 60/5 = 12
Width = 12
Length = 4 * 12 + 10 = 48 +10 = 58

Solve for
y
y in
2
x
+
y
=
8
2x+y=8.
y
=
8
−
2
x
y=8−2x
2 Substitute
y
=
8
−
2
x
y=8−2x into
4
x
+
6
y
=
24
4x+6y=24.
−
8
x

48
=
24
−8x+48=24
3 Solve for
x
x in
−
8
x
+
48
=
24
−8x+48=24.
x
=
3
x=3
4 Substitute
x
=
3
x=3 into
y
=
8
−
2
x
y=8−2x.
y
=
2
y=2
5 Therefore,
x
=
3
y
=
2
x=3
y=2
look in comments to read it better but x=3 y=2 hope this helps :)
-2x+6y=6
-7x+8y=-5
2(7x+8y=-5)
-7(-2x+6y=6)
Distribute
14x+16y=-10
14x-42y=-42
eliminate
-26y=-32
divide
y=1.2
-2x+6(1.2)=6
-2x+7.4=6
subtract 7.4 on both sides
-2x=-1.4
divide
x=0.7
I believe this is right
