X+y=2(x-y)
x+y=2x-2y
3y=x
x-2y=2
then,substitute
(3y)-2y=2
y=2
so,x=3(2)
x=6
x the largest
y the smallest

The common factors are:

Therefore, the Greatest Common Factor (GCF) is 9
b) To find the factor 63 - 36
Answer:
x= 2
z=117
Step-by-step explanation:
To find x:
63=(6x+51)
Simplify/ Subtraction property
12=6x
Evaluate/ division property
2=x
To find z:
