The answer is: t = 1
You need to separate t from everything to figure out what it is.
Step 1: Subtract 9 from both sides, so we get 7 - 2t = 5t
Step 2: Add 2t to both sides, so we get 7 = 7t.
Step 3: Divide by 7, meaning t = 1.
Next you should check your work. If we plug 1 in for t, we get 14 = 14, so the answer is correct.
Hope this helps!
