This student made an error with the disruptive property. What did s/he do wrong?

• You can't drop down a -16; You need to keep it positive

• You should only multiply the -2 & 8m; the 8 should stay the same

• You need to multiply -2 to both parts inside the parenthesis; -2*8m is -16m and -2*8 is -16

• You should divide -2 from both sides first

This student subtracted 2 from both sides of the equation. What should s/he have done?

• Nothing; This is correct

• S/He should have added a -2 to both sides

• S/He should have added 2 to both sides

• Subtracted 2x instead of 2
