Answer:

Hi!

To solve this we can begin by adding 20 to both sides

30t = 90

Next we divide both sides by 30

t = 3

30t-20=70
+20 +20
____________
90.
30t 90
Divide by 30 on each

T=3

The -20 and +20 cancel out so you just forget about those

The 30t cancels out with the divided by 30 again so it becomes t and 30x3=90
