Answer:

s = 2 and t = 3

Step-by-step explanation:

<u>Assuming you were suppose to type s instead of a,</u>

12s + 10t = 54 -- (1)

6s + 10t = 42 -- (2)

(1) - (2) : 6s = 12

               s = 2 -- (3)

Substituting (3) into (2),

12 + 10t = 42

10t = 30

t = 3 -- (4)

Therefore, s = 2 and t = 3
