Olivia's work and solution to the equation -6x+ 11 =43 is shown. identify each error in olivia's work and explain what she should have done instead .

-6x + 11 = 43
+ 11 +11
-6x =54
-6x/6 = 54/6
x =9

She had to subtract 11 from both sides of equation
-6x + 11 = 43
       - 11    - 11
-6x = 32
-6x/-6 = 32/-6
x = 

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
