Answer:
Given: ABCD is a parallelogram,
In which E ∈ BC and F lies on the extension of DC,
Such that line segment EF goes through the vertex A.
To prove:
Proof:
Since, By the definition of parallelogram,
By the Alternative interior angle theorem,
Also, ( vertically opposite angles )
Thus, By AA similarity postulate,
Hence proved.

-2x-8(-3+5)=-18
-2x+24-40=-18
-2x=-2
x=1
-2(1)-8y=-18
-2-8y=-18
-8y=-16
y=2
ANSWER:
x=1 y=2
x=smaller number
y=larger number
x+y=12
y=3x-6
Let's begin with the first equation...
x+y=12
Let's substitute...
x+(3x-6)=12
4x-6=12
Let's add 6 to both sides as we proceed to isolate x...
6+4x-6=12+6
4x=18
Let's divide both sides by 4...
(4x)/4=18/4
x=9/2=4.5---smaller number
12-4.5=7.5s larger number
