\left(x-4\right)\times 5x+\left(x-2\right)\left(2x-5\right)=\left(x+3\right)\left(7x-10\right)
Variable x cannot be equal to any of the values -3,2,4 since division by zero is not defined. Multiply both sides of the equation by \left(x-4\right)\left(x-2\right)\left(x+3\right), the least common multiple of x^{2}+x-6,x^{2}-x-12,x^{2}-6x+8.
\left(5x-20\right)x+\left(x-2\right)\left(2x-5\right)=\left(x+3\right)\left(7x-10\right)
Use the distributive property to multiply x-4 by 5.
5x^{2}-20x+\left(x-2\right)\left(2x-5\right)=\left(x+3\right)\left(7x-10\right)
Use the distributive property to multiply 5x-20 by x.
5x^{2}-20x+2x^{2}-9x+10=\left(x+3\right)\left(7x-10\right)
Use the distributive property to multiply x-2 by 2x-5 and combine like terms.
7x^{2}-20x-9x+10=\left(x+3\right)\left(7x-10\right)
Combine 5x^{2} and 2x^{2} to get 7x^{2}.
7x^{2}-29x+10=\left(x+3\right)\left(7x-10\right)
Combine -20x and -9x to get -29x.
7x^{2}-29x+10=7x^{2}+11x-30
Use the distributive property to multiply x+3 by 7x-10 and combine like terms.
7x^{2}-29x+10-7x^{2}=11x-30
Subtract 7x^{2} from both sides.
-29x+10=11x-30
Combine 7x^{2} and -7x^{2} to get 0.
-29x+10-11x=-30
Subtract 11x from both sides.
-40x+10=-30
Combine -29x and -11x to get -40x.
-40x=-30-10
Subtract 10 from both sides.
-40x=-40
Subtract 10 from -30 to get -40.
x=\frac{-40}{-40}
Divide both sides by -40.
x=1
Divide -40 by -40 to get 1.
