2\left(2x-1\right)\times \frac{7}{2}-2\left(x-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 2\left(2x-1\right), the least common multiple of 2,2x-1.
\left(4x-2\right)\times \frac{7}{2}-2\left(x-5\right)=3\left(2x-1\right)
Use the distributive property to multiply 2 by 2x-1.
14x-7-2\left(x-5\right)=3\left(2x-1\right)
Use the distributive property to multiply 4x-2 by \frac{7}{2}.
14x-7-2x+10=3\left(2x-1\right)
Use the distributive property to multiply -2 by x-5.
12x-7+10=3\left(2x-1\right)
Combine 14x and -2x to get 12x.
12x+3=3\left(2x-1\right)
Add -7 and 10 to get 3.
12x+3=6x-3
Use the distributive property to multiply 3 by 2x-1.
12x+3-6x=-3
Subtract 6x from both sides.
6x+3=-3
Combine 12x and -6x to get 6x.
6x=-3-3
Subtract 3 from both sides.
6x=-6
Subtract 3 from -3 to get -6.
x=\frac{-6}{6}
Divide both sides by 6.
x=-1
Divide -6 by 6 to get -1.
