3\left(2x+5\right)=3\left(x-3\right)\times \frac{1}{3}+3\times 4
Variable x cannot be equal to 3 since division by zero is not defined. Multiply both sides of the equation by 3\left(x-3\right), the least common multiple of x-3,3.
6x+15=3\left(x-3\right)\times \frac{1}{3}+3\times 4
Use the distributive property to multiply 3 by 2x+5.
6x+15=x-3+3\times 4
Multiply 3 and \frac{1}{3} to get 1.
6x+15=x-3+12
Multiply 3 and 4 to get 12.
6x+15=x+9
Add -3 and 12 to get 9.
6x+15-x=9
Subtract x from both sides.
5x+15=9
Combine 6x and -x to get 5x.
5x=9-15
Subtract 15 from both sides.
5x=-6
Subtract 15 from 9 to get -6.
x=\frac{-6}{5}
Divide both sides by 5.
x=-\frac{6}{5}
Fraction \frac{-6}{5} can be rewritten as -\frac{6}{5} by extracting the negative sign.
