Question 641372

Please help me solve this [[[ (x-7/x+5)=(x-6/x+4) ]]]


{{{(x - 7)/(x + 5) = (x - 6)/(x + 4)}}}


(x - 7)(x + 4) = (x + 5)(x - 6) ---- Cross-multiplying


{{{x^2 - 3x - 28 = x^2 - x - 30}}}


{{{x^2 - x^2 - 3x + x = - 30 + 28}}}


- 2x = - 2


{{{x = (- 2)/- 2}}}, or {{{highlight_green(x = 1)}}} 


You can do the check, I'm sure!!
