\left(x+1\right)\left(x+3\right)+\left(x-2\right)\left(x+1\right)\times 2=\left(x-2\right)\left(x+3\right)\times 3
Variable x cannot be equal to any of the values -3,-1,2 since division by zero is not defined. Multiply both sides of the equation by \left(x-2\right)\left(x+1\right)\left(x+3\right), the least common multiple of x-2,x+3,x+1.
x^{2}+4x+3+\left(x-2\right)\left(x+1\right)\times 2=\left(x-2\right)\left(x+3\right)\times 3
Use the distributive property to multiply x+1 by x+3 and combine like terms.
x^{2}+4x+3+\left(x^{2}-x-2\right)\times 2=\left(x-2\right)\left(x+3\right)\times 3
Use the distributive property to multiply x-2 by x+1 and combine like terms.
x^{2}+4x+3+2x^{2}-2x-4=\left(x-2\right)\left(x+3\right)\times 3
Use the distributive property to multiply x^{2}-x-2 by 2.
3x^{2}+4x+3-2x-4=\left(x-2\right)\left(x+3\right)\times 3
Combine x^{2} and 2x^{2} to get 3x^{2}.
3x^{2}+2x+3-4=\left(x-2\right)\left(x+3\right)\times 3
Combine 4x and -2x to get 2x.
3x^{2}+2x-1=\left(x-2\right)\left(x+3\right)\times 3
Subtract 4 from 3 to get -1.
3x^{2}+2x-1=\left(x^{2}+x-6\right)\times 3
Use the distributive property to multiply x-2 by x+3 and combine like terms.
3x^{2}+2x-1=3x^{2}+3x-18
Use the distributive property to multiply x^{2}+x-6 by 3.
3x^{2}+2x-1-3x^{2}=3x-18
Subtract 3x^{2} from both sides.
2x-1=3x-18
Combine 3x^{2} and -3x^{2} to get 0.
2x-1-3x=-18
Subtract 3x from both sides.
-x-1=-18
Combine 2x and -3x to get -x.
-x=-18+1
Add 1 to both sides.
-x=-17
Add -18 and 1 to get -17.
x=17
Multiply both sides by -1.
