Question

3250/x-5 - 3150/x = 5

Answer 1

\[\frac{ 3250 }{ x-5 } - \frac{ 3150 }{ x } = 5\]

Answer 2

@kohai

Answer 3

subtract first

Answer 4

\[\frac{3250x-3150(x-5)}{(x-5)x}=5\]

Answer 5

then \[3250x-3150(x-5)=5x(x-5)\]
divide both sides by \(5\)
multiply out
combine like terms
solve the resulting quadratic

Answer 6

x^2 - 25x = 3150 = 0

Answer 7

\[ 3250x-3150(x-5)=5x(x-5) \\ 650x -630x+3150=x^2-5x \\
20x+3150= x^2 -5x \\
x^2 -5x-20x -3150 = 0 \\
x^2 -25x -3150=0
\]

Answer 8

factoring 3150 looks painful. try 70 as a factor.
