1\left(x+2\right)\times 7x+\left(x-3\right)\left(x+2\right)\left(-1\right)=\left(x-3\right)\times 2\left(3x-1\right)
Variable x cannot be equal to any of the values -2,3 since division by zero is not defined. Multiply both sides of the equation by \left(x-3\right)\left(x+2\right), the least common multiple of x-3,x+2.
7\left(x+2\right)x+\left(x-3\right)\left(x+2\right)\left(-1\right)=\left(x-3\right)\times 2\left(3x-1\right)
Multiply 1 and 7 to get 7.
\left(7x+14\right)x+\left(x-3\right)\left(x+2\right)\left(-1\right)=\left(x-3\right)\times 2\left(3x-1\right)
Use the distributive property to multiply 7 by x+2.
7x^{2}+14x+\left(x-3\right)\left(x+2\right)\left(-1\right)=\left(x-3\right)\times 2\left(3x-1\right)
Use the distributive property to multiply 7x+14 by x.
7x^{2}+14x+\left(x^{2}-x-6\right)\left(-1\right)=\left(x-3\right)\times 2\left(3x-1\right)
Use the distributive property to multiply x-3 by x+2 and combine like terms.
7x^{2}+14x-x^{2}+x+6=\left(x-3\right)\times 2\left(3x-1\right)
Use the distributive property to multiply x^{2}-x-6 by -1.
6x^{2}+14x+x+6=\left(x-3\right)\times 2\left(3x-1\right)
Combine 7x^{2} and -x^{2} to get 6x^{2}.
6x^{2}+15x+6=\left(x-3\right)\times 2\left(3x-1\right)
Combine 14x and x to get 15x.
6x^{2}+15x+6=\left(2x-6\right)\left(3x-1\right)
Use the distributive property to multiply x-3 by 2.
6x^{2}+15x+6=6x^{2}-20x+6
Use the distributive property to multiply 2x-6 by 3x-1 and combine like terms.
6x^{2}+15x+6-6x^{2}=-20x+6
Subtract 6x^{2} from both sides.
15x+6=-20x+6
Combine 6x^{2} and -6x^{2} to get 0.
15x+6+20x=6
Add 20x to both sides.
35x+6=6
Combine 15x and 20x to get 35x.
35x=6-6
Subtract 6 from both sides.
35x=0
Subtract 6 from 6 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 35 is not equal to 0, x must be equal to 0.
