6\left(3x-1\right)=3x+12+\left(x+3\right)\times 7
Variable x cannot be equal to any of the values -4,-3 since division by zero is not defined. Multiply both sides of the equation by 6\left(x+3\right)\left(x+4\right), the least common multiple of x^{2}+7x+12,2x+6,6x+24.
18x-6=3x+12+\left(x+3\right)\times 7
Use the distributive property to multiply 6 by 3x-1.
18x-6=3x+12+7x+21
Use the distributive property to multiply x+3 by 7.
18x-6=10x+12+21
Combine 3x and 7x to get 10x.
18x-6=10x+33
Add 12 and 21 to get 33.
18x-6-10x=33
Subtract 10x from both sides.
8x-6=33
Combine 18x and -10x to get 8x.
8x=33+6
Add 6 to both sides.
8x=39
Add 33 and 6 to get 39.
x=\frac{39}{8}
Divide both sides by 8.
