Answer: Subtract 18 on both sides is wrong. Its supposed to be add 18 on both sides.
Step-by-step explanation:
She subtracted instead of adding.
2x-18=10
You add 18 to both sides
So it would be 2x=28
Then you divide 2 on both sides so x=14
2x-18=10
You add 18 to both sides
So it would be 2x=28
Then you divide 2 on both sides so x=14
