Question

Solve by
substitution method
s-t=3​

Answer 1

Answer:

Given:-

s-t=3

s/3+t/2=6

solution:-

=>S-t=3... 1

=>S/3+t/2=6...2

from equation (1),we get S=t+3

putting this value in equation (2) , we get

=>t+3/3+t/2=6

=> 2t+6+3t=36

=> 5t=30

=>t=30/5

=>t=6... (4)

now substitute (4) in (3)

S=3+6

S=9
