She walks 3 kilometers because 60 divided by 20 is 3
First, distribute -2 to all terms within the parenthesis
-2(2x) = -4x
-2(3) = -6
-4x - 6 + 11 = 11 - 3x
SImplify. Combine like terms
-4x (-6 + 11) = 11 - 3x
-4x + 5 = 11 - 3x
Isolate the x. Add 3x to both sides, and subtract 5 from both sides
-4x (+3x) + 5 (-5) = 11 (-5) - 3x (+ 3x)
-4x + 3x = 11 - 5
Simplify
-x = 6
Isolate the x. Divide -1 from both sides
-x/-1 = 6/-1
x = -6
-6 is your answer
