4 - (2x - 9)= -19 is the same as 4 - 1(2x - 9)= -19


4-1%282x-9%29=-19 Start with the given equation.


4-2x%2B9=-19 Distribute.


-2x%2B13=-19 Combine like terms on the left side.


-2x=-19-13 Subtract 13 from both sides.


-2x=-32 Combine like terms on the right side.


x=%28-32%29%2F%28-2%29 Divide both sides by -2 to isolate x.


x=16 Reduce.
