Answer:


(15)/(251)

Explanation:

3s+2t=5

124s-x=5 (multiply by 2)

so, 3s+2t=5

248s-2t=10 (we then add the two equations)

,251s=15

s= 15/251

and if you want the "t" then you will put "s" with "15/251"

3×(15/251)+2t=5

= 45/251+2t=5

= 2t=5-(45/251)

= 2t= 1210/251

= t= (1210/251)÷2

,t=605/251

hope this helps
