Answer:

t-20

Step-by-step explanation:

k+20=t

Subtract 20 from both sides:

k= t-20

Answer:

K=t-20

Step-by-step explanation:

20=K

We move all terms to the left:

20-(K)=0

We add all the numbers together, and all the variables

1K+20=0

We move all terms containing K to the left, all other terms to the right

K=-20

K=-20/-1

K=t-20
