5x-4=10x-16
Multiply both sides of the equation by 2.
5x-4-10x=-16
Subtract 10x from both sides.
-5x-4=-16
Combine 5x and -10x to get -5x.
-5x=-16+4
Add 4 to both sides.
-5x=-12
Add -16 and 4 to get -12.
x=\frac{-12}{-5}
Divide both sides by -5.
x=\frac{12}{5}
Fraction \frac{-12}{-5} can be simplified to \frac{12}{5} by removing the negative sign from both the numerator and the denominator.
