Answer 1

Mikayla subracted 4 from both sides, not add. She was supposed to add so that the -4 can cancel out.

The correct answer would be x=1

Answer 2

Mikayla subtracted 4 from both sides in the beginning when she should've added it to both sides to cancel it out on the right. the correct answer should actually be x=1
