The left and right  hand margins on a sheet of paper are both 1.25 inches wide. The total width of the sheet t of paper is 8.5 inches. Write and solve an equation to find the width of the text area that lies betwen the margins.

and what is your thinking on this?

Let t = the width of the text area.
t = 8.5  2.5 
Thank you.
