3\left(x+3\right)+2\left(15x-3\right)=6x+24
Multiply both sides of the equation by 6, the least common multiple of 2,3.
3x+9+2\left(15x-3\right)=6x+24
Use the distributive property to multiply 3 by x+3.
3x+9+30x-6=6x+24
Use the distributive property to multiply 2 by 15x-3.
33x+9-6=6x+24
Combine 3x and 30x to get 33x.
33x+3=6x+24
Subtract 6 from 9 to get 3.
33x+3-6x=24
Subtract 6x from both sides.
27x+3=24
Combine 33x and -6x to get 27x.
27x=24-3
Subtract 3 from both sides.
27x=21
Subtract 3 from 24 to get 21.
x=\frac{21}{27}
Divide both sides by 27.
x=\frac{7}{9}
Reduce the fraction \frac{21}{27} to lowest terms by extracting and canceling out 3.
