Answer:
<h2>t=-1</h2>
Basic fact:
<em> a + and a - make a -</em>
Step-by-step explanation:
6 + -3 = 3t + 6
6+-3=6-3
6-3=3
3= 3t+6
-6
-3=3t
divide by 3
-1=t
You missed one final step, no worries! When finding the percent off, subtract the value you got after dividing the price after discount by the initial price from 100.

35% off
