4/(x-5)+5/2=9/(x+5)

From here: \[\frac{4}{x-5}+\frac{5}{2}=\frac{9}{x+5}\] The trick is to use your GCD (greatest common denominator), multiply it to both sides of the equation, and then cancel out stuff: \[\frac{4(2)(x+5)\cancel{(x-5)}}{\cancel{x-5}}+\frac{5\cancel{(2)}(x+5)(x-5)}{\cancel{2}}=\frac{9(2)\cancel{(x+5)}(x-5)}{\cancel{x+5}}\]

Remember to F.O.I.L. the middle term (first outer middle last)

so the correct answer is x=1 @agentx5 i used the quadractic formula to finish the equation

That is correct. -1 + 5/2 = 3/2 ;-)
