Tim said that to solve the equation x-2=9, he would have to subtract 2 from both sides of the equation. Is Tim correct? Explain.
Answered by Majiri
No he is not.
If you subtract two from the left hand side you get -4.

So to solve the equation you add 2 to both sides

Thank you!!

Yes, because - 2 + 2 will be a variable and 9 + 2 will be 11 so the answer would be x=11.
