2\times 2-\left(x-3\right)=4x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2x, the least common multiple of x,2x.
4-\left(x-3\right)=4x
Multiply 2 and 2 to get 4.
4-x+3=4x
To find the opposite of x-3, find the opposite of each term.
7-x=4x
Add 4 and 3 to get 7.
7-x-4x=0
Subtract 4x from both sides.
7-5x=0
Combine -x and -4x to get -5x.
-5x=-7
Subtract 7 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-7}{-5}
Divide both sides by -5.
x=\frac{7}{5}
Fraction \frac{-7}{-5} can be simplified to \frac{7}{5} by removing the negative sign from both the numerator and the denominator.
