45\left(\frac{1}{3}+\frac{x}{5}\right)-10=3\left(2x-\frac{1}{3}\right)
Multiply both sides of the equation by 15, the least common multiple of 3,5.
45\left(\frac{5}{15}+\frac{3x}{15}\right)-10=3\left(2x-\frac{1}{3}\right)
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3 and 5 is 15. Multiply \frac{1}{3} times \frac{5}{5}. Multiply \frac{x}{5} times \frac{3}{3}.
45\times \frac{5+3x}{15}-10=3\left(2x-\frac{1}{3}\right)
Since \frac{5}{15} and \frac{3x}{15} have the same denominator, add them by adding their numerators.
3\left(5+3x\right)-10=3\left(2x-\frac{1}{3}\right)
Cancel out 15, the greatest common factor in 45 and 15.
15+9x-10=3\left(2x-\frac{1}{3}\right)
Use the distributive property to multiply 3 by 5+3x.
5+9x=3\left(2x-\frac{1}{3}\right)
Subtract 10 from 15 to get 5.
5+9x=6x+3\left(-\frac{1}{3}\right)
Use the distributive property to multiply 3 by 2x-\frac{1}{3}.
5+9x=6x-1
Cancel out 3 and 3.
5+9x-6x=-1
Subtract 6x from both sides.
5+3x=-1
Combine 9x and -6x to get 3x.
3x=-1-5
Subtract 5 from both sides.
3x=-6
Subtract 5 from -1 to get -6.
x=\frac{-6}{3}
Divide both sides by 3.
x=-2
Divide -6 by 3 to get -2.
