Get a common denominator.
1/2 = 5/10
2/5 = 4/10
1/2 is greater
14x - (2x - y) - y
14x + (-1(2x - y)) - y
14x + (-1(2x) - 1(-y)) - y
14x + (-2x + y) - y
14x + 1(-2x + y) - y
14x + 1(-2x) + 1(y) - y
14x - 2x + y - y
14x - 2x
12x
X=5, should be right correct me if i’m wrong.
we are given

Firstly, we will factor numerators and denominators

we can see that
n^2 -6 is factor on both numerator and denominator
so, it will get cancelled
and n^2 -6 can not be equal to 0
so, one of restriction is


we can simplify it

we know that denominator can not be zero


so, option-B.......Answer
Hey there! :D
If 20 is 25% of a number,
we know that it is a quarter of a number.
20*4= 80
20 is 25% of 80.
I hope this helps!
