x+6 x
--- = ---
x+2 x-1
:
=
:
Cross multiply
(x+6)(x-1) = x(x+2)
:
FOIL (x+6)(x-1)
x^2 + 5x - 6 = x^2 + 2x
:
Combine like terms on the left:
x^2 - x^2 + 5x - 2x - 6 = 0
3x - 6 = 0
3x = +6; added 6 to both sides
x =
x = +2
:
Check solution in original equation, substitute 2 for x
=
=
= ; proves our solution of x=2
