solve

x+21/x+3<2

x+21/x+3 - 2(x+3)/x+3 <0

x+21-2(x-3)/x+3<0

x+21-2x-6/x+3<0

answer

15-x/x-3<0(is this right?)

You are close. They want you to find the values of x so that the equation the inequality is true. So just do that and you have your answer. I'll be happy to check you answer again when you are done.

Just a note. When you are writing fractions horizontally, you have to put parenthesis around the numerator and the denominator. Otherwise like for your x+21/x+3

It's the same as x + (21/x) + 3. The proper way to do it is (x+21)/(x+3) but anyways its very minor and you probably don't right fractions horizontally in real life, normally.

Is this right?

(15-x)/(x-3)<0

15-x<0

-x<-15

answer is x>15

x+3<0

answer is x<-3
