Start by multiplying the right side by (x-4) to get rid of the fraction. After you do that you will have (x-7/3x+6)(x-4) = -1. Foil out the left side to get x^2-7/3x^2+6x-4x+7/3x-24=-1. After you get that all you have to do is simplify and you get -4/3x^2+10/3x-23 = 0

multiply by x to eliminate the x on the main appropriate area of equation 4x/3x-2 + 7x/3x = a million straight forward denominator of (3x)(3x-2) 4x(3x) + 7x(3x-2) = (3x)(3x-2) eliminate brackets and circulate each and everything to the left area 24x^2 - 8x = 0 divide by 8x 3x -a million = 0 3x=a million x = a million/3

- 7 / (3x + 6) = - 1 / (x - 4)
- 7x + 28 = - 3x - 6
4x = 22
x = 11/2

Multiply by 3 on both sides:
-7x+18=-3/x-12
The multiply by x:
-7x^2+18x=-3-12x
You got a quadratic equation, write in standard form:
-7x^2+30x+3=0
Use quadratic formula:
x=(900+-sqrt(984))/-14
