Answer:

X= 10

Step-by-step explanation:

11-2x = -9 first we need have x alone on the left hand side if we want to find x

11-2x= -9

-2x= -9-11 we take 11 to the right hand side the additive Inverse rule

-2x= -20 after reaching this step we divide both sides by 2 because we want to leave x alone
