19 - 2k = 3k - 1
+3k +3k
19 + 1k = -1
-19 -19
k = -20
Find the error
There is no error
They should have subtracted 3 to both sides
They should have subtracted 2x to both sides
They should have divided 7 to both sides
The answer should be 6/7
5 + 2(n + 1) = 2n
Bill says the first step is the add 5 + 2 to get
7(n + 1) = 2n
Bill is correct
Bill is wrong. He should have subtracted 5 to both sides first.
Bill wrong. He should have distributed the 2 first.
Bill is wrong. He should have divided 2 to both sides first.
