x-6x-9=5x+2\left(2x-5\right)
Use the distributive property to multiply -3 by 2x+3.
-5x-9=5x+2\left(2x-5\right)
Combine x and -6x to get -5x.
-5x-9=5x+4x-10
Use the distributive property to multiply 2 by 2x-5.
-5x-9=9x-10
Combine 5x and 4x to get 9x.
-5x-9-9x=-10
Subtract 9x from both sides.
-14x-9=-10
Combine -5x and -9x to get -14x.
-14x=-10+9
Add 9 to both sides.
-14x=-1
Add -10 and 9 to get -1.
x=\frac{-1}{-14}
Divide both sides by -14.
x=\frac{1}{14}
Fraction \frac{-1}{-14} can be simplified to \frac{1}{14} by removing the negative sign from both the numerator and the denominator.
