ok i know this is easy just forgot a few rules along the way the expression is

1+1= 2

2 - t 2+t

how would i go about this i thought you make it into 2 equations that = 2 ie.

1=2 ,1= 2 then solve for t in both but i came up with 3 and -3

2-t 2+t

when i checked my work they did not equat 2 but -2

please help

thank you
