It would be much appreciated if someone could solve this for me :)
x/(x+1) < x/(x-1)
x/(x+1) < x/(x-1)
-
x/(x+1) < x/(x-1)
Don't let the inequality confuse you. just act like the inequality is a equal sign.
Once you understand, then cross-multiply.
x(x - 1) < x(x + 1)
Distribute the x
x^2 - x < x^2 + x
Subtract x^2 to both sides. Add x to both sides.
x^2 - x^2 - x + x < x^2 - x^2 + x + x
0 < 2x
Divide 2 to both sides.
0 / 2 < 2x / 2
0 < x
The answer is 0 < x

richard has it right. just dont forget that with an inequality whenever you divide or multiply by a negative number the sign changes direction.
