6 - 9x = 5x - 10x - 10
6 + 10 = -5x + 9x
16 = 4x
X = 4

6-9x=5x-10x-10

Combine Like Terms:


-9x+6=(5x+-10x)+(-10)


-9x+6=-5x-10

Add 5x to both sides:


-9x+6+5x=-5x-10+5x


-4x+6=-10

Subtract 6 from both sides:


-4x+6-6=-10-6


-4x=-16

Divide both sides by -4:


(-4x)/(-4) =(-16)/(-4)


\fbox{x = 4}
