x = 5, y = 25
15.) Simplify the expression if possible 2x^2 - 4x / x - 2
17.) For what values of the variable x is the rational
expression undefined: 8/(x + 2)
18.) Simplify the expression 5x/2 * 1/x
19.) Simplify the expression 12x/5 / 6x/7

2]cross multiply :x^2=36
:x=6
10]x=my
15]x-2
take 2x common frm nr thf x-2 gets cancelled
17]-2 because -2+2 =0
18]5/2
19]14/5
20]19+x/3x
if u dont mind id like to know you are in what grade
21]1/[x+2]
22]3x+2/x^2
24]3x+2-[1/x]
25]x+6 because eq gets fctrzed to x+6 x-3

2) x^2 = 36
x=6
17) if x= -2, since it would cause 8/(-2+2) or 8/0.
Sorry, but it's late and I did the simplest ones I could see.
