(1/10) (x+11) = -2 (8-x)      multiply both sides by 10 to clear the fraction

 

10 (1/10)(x + 11) =  10 (-2)(8 - x)

 

1(x + 11)   =  -20( 8 - x)

 

x + 11  =  -160 + 20x     add 160 to both sides, subtract x from both sides

 

171  =  19x     divide both sides by 19

 

9  = x 

 

 

cool cool cool
