Question

please help , how would you solve this

Answer 1

for the first one:
$t \: - \: 2e = 20$
you change the subtract 2 to add 2 on both sides. so it looks like the picture above. Then you would add 20 + 2 to equal 22. Then you divide that by 1 (from the t). that equals 22, so thats the answer.
$t = 22$
