5\left(3a+1\right)x=3a\left(5x-3\right)
Multiply both sides of the equation by 15, the least common multiple of 3,5.
\left(15a+5\right)x=3a\left(5x-3\right)
Use the distributive property to multiply 5 by 3a+1.
15ax+5x=3a\left(5x-3\right)
Use the distributive property to multiply 15a+5 by x.
15ax+5x=15ax-9a
Use the distributive property to multiply 3a by 5x-3.
15ax+5x-15ax=-9a
Subtract 15ax from both sides.
5x=-9a
Combine 15ax and -15ax to get 0.
-9a=5x
Swap sides so that all variable terms are on the left hand side.
\frac{-9a}{-9}=\frac{5x}{-9}
Divide both sides by -9.
a=\frac{5x}{-9}
Dividing by -9 undoes the multiplication by -9.
a=-\frac{5x}{9}
Divide 5x by -9.
5\left(3a+1\right)x=3a\left(5x-3\right)
Multiply both sides of the equation by 15, the least common multiple of 3,5.
\left(15a+5\right)x=3a\left(5x-3\right)
Use the distributive property to multiply 5 by 3a+1.
15ax+5x=3a\left(5x-3\right)
Use the distributive property to multiply 15a+5 by x.
15ax+5x=15xa-9a
Use the distributive property to multiply 3a by 5x-3.
15ax+5x-15xa=-9a
Subtract 15xa from both sides.
5x=-9a
Combine 15ax and -15xa to get 0.
\frac{5x}{5}=-\frac{9a}{5}
Divide both sides by 5.
x=-\frac{9a}{5}
Dividing by 5 undoes the multiplication by 5.
