\left(2x-1\right)\times 3-\left(2x+1\right)\times 2-\left(x+3\right)=0
Variable x cannot be equal to any of the values -\frac{1}{2},\frac{1}{2} since division by zero is not defined. Multiply both sides of the equation by \left(2x-1\right)\left(2x+1\right), the least common multiple of 2x+1,2x-1,4x^{2}-1.
6x-3-\left(2x+1\right)\times 2-\left(x+3\right)=0
Use the distributive property to multiply 2x-1 by 3.
6x-3-\left(4x+2\right)-\left(x+3\right)=0
Use the distributive property to multiply 2x+1 by 2.
6x-3-4x-2-\left(x+3\right)=0
To find the opposite of 4x+2, find the opposite of each term.
2x-3-2-\left(x+3\right)=0
Combine 6x and -4x to get 2x.
2x-5-\left(x+3\right)=0
Subtract 2 from -3 to get -5.
2x-5-x-3=0
To find the opposite of x+3, find the opposite of each term.
x-5-3=0
Combine 2x and -x to get x.
x-8=0
Subtract 3 from -5 to get -8.
x=8
Add 8 to both sides. Anything plus zero gives itself.
