-\left(x-5\right)+2x\left(-1\right)=3x
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 2x,2.
-x+5+2x\left(-1\right)=3x
To find the opposite of x-5, find the opposite of each term.
-x+5-2x=3x
Multiply 2 and -1 to get -2.
-3x+5=3x
Combine -x and -2x to get -3x.
-3x+5-3x=0
Subtract 3x from both sides.
-6x+5=0
Combine -3x and -3x to get -6x.
-6x=-5
Subtract 5 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-5}{-6}
Divide both sides by -6.
x=\frac{5}{6}
Fraction \frac{-5}{-6} can be simplified to \frac{5}{6} by removing the negative sign from both the numerator and the denominator.
