We need to analyze Lorena's steps
Step 1 is correct that is she correctly distributed –3 to the parentheses.
Therefore, she got 5k-6k+2-9=0
Step 2 is correct that is she combined like terms 5k and 2k
Therefore, she got -k-7=0
Step 3 is not correct that is she did not use the multiplication property of equality.
Step 4 is correct that is she should have multiplied both sides by -1 to isolate the variable. so, to get k= -7.
