3\times 1\times \frac{1}{3}\left(2x+5\right)=3\left(2x-1\right)
Variable x cannot be equal to \frac{1}{2} since division by zero is not defined. Multiply both sides of the equation by 3\left(2x-1\right), the least common multiple of 2x-1,3.
3\times \frac{1}{3}\left(2x+5\right)=3\left(2x-1\right)
Multiply 3 and 1 to get 3.
2x+5=3\left(2x-1\right)
Multiply 3 and \frac{1}{3} to get 1.
2x+5=6x-3
Use the distributive property to multiply 3 by 2x-1.
2x+5-6x=-3
Subtract 6x from both sides.
-4x+5=-3
Combine 2x and -6x to get -4x.
-4x=-3-5
Subtract 5 from both sides.
-4x=-8
Subtract 5 from -3 to get -8.
x=\frac{-8}{-4}
Divide both sides by -4.
x=2
Divide -8 by -4 to get 2.
