Answer:
s=5 b=6
Step-by-step explanation:
2s + 3b = 28.
3s + 2b = 27
First, multiply the first eqn by 3 and multiply the first eqn by 2.
FROM FIRST EQUATION
3 (2s + 3b= 28)
6s + 9b = 84.
FROM SECOND EQUATION
2 (3s+2b =27)
6s + 4b = 54
FIRST EQUATION - SECOND EQUATION
(6s+9b)-(6s+4b) = 84-54
6s+9b-6s-4b = 30
6s-6s+9b-4b=30
5b=30
b=6
Then, substitute b=6 into the first eqn.( the second eqn also can be used)
6s+9(6) =84
6s + 54 = 84
6s = 84-54
6s = 30
s=5
Thank you.
