Question 4712
-4 (2x+ 1) - (x-2) = -11  
The first step is distributive property.  

-8x - 4 - x + 2 = -11  


Combine like terms on the left side.
-9x - 2 = -11 


Add +2 to each side of the equation:
-9x - 2 + 2 = -11 + 2
-9x = - 9


Divide each side by -9:
{{{-9x/(-9) = -9/(-9) }}}
{{{x= 1}}}


Check in the original problem:

-4(2x+ 1) - (x-2) = -11
-4(2*1 + 1) - (1-2) = -11
-4 (3) - (-1) = -11
-12 + 1 = -11
-11 = -11 It checks!
