I believe the person meant use pemdas! (order of opporations.)
you know what that is, right ? if you have questions feel free to message me!
You first want to get rid of 2, so you divide two on both sides canceling the two on the left and getting x-1=5. then you add 1 to both sides getting x=6.
Hope this helps!
