Hello!
-2 + d = 97
d = 97 + 2
d = 99
I hope this helps you! Have a lovely day!

Hi! So if this a standard one step equation, you must move the -2 over to the 97 to isolate the "d" variable. To do this, you must do the opposite operation, which is +2, and do that do both sides. Once you do it to both sides it should be D=99.
The work should look like this:
-2+d=97
+2 +2
d=99
