Please help me solve this:
:
Since you have a single fraction on each side of the = sign, you can cross multiply:
:
(3x+10)*(4x+3) = x(7x-4)
:
12x^2 + 49x + 30 = 7x^2 - 4x
:
12x^2 - 7x^2 + 49x + 4x + 30 = 0
:
5x^2 + 53x + 30 = 0
:
Factors to:
(5x + 3)(x + 10) = 0
:
x = -10
and
5x = -3
x = -3/5
:
:
Check solution using x = -.6
=
:
-1 = -1; confirms x = -3/5; you can check it with x = -10
