4-5x=4x-10
Multiply both sides of the equation by 2.
4-5x-4x=-10
Subtract 4x from both sides.
4-9x=-10
Combine -5x and -4x to get -9x.
-9x=-10-4
Subtract 4 from both sides.
-9x=-14
Subtract 4 from -10 to get -14.
x=\frac{-14}{-9}
Divide both sides by -9.
x=\frac{14}{9}
Fraction \frac{-14}{-9} can be simplified to \frac{14}{9} by removing the negative sign from both the numerator and the denominator.
