Solution
Given:-
- s - t = 3_______(1)
- s/3 + t/2 = 6_____(2)
Find :-
- Value of s & t by Substitution method,
Explanation
Substitution Method
By, Equ (1)
==> s = t + 3_________(3)
By, Equ (2)
==> 2s + 3t = 36_______(4)
Keep Value by equ(3) in equ(4)
==> 2(t + 3) + 3t = 36
==> 2t + 3t + 6 = 36
==> 5t = 36 - 6
==> 5t = 30
==> t = 30/5
==> t = 6
keep Value of t in equ(3)
==> s = 6 + 3
==. s = 9
Hence
- Value of s = 9
- Value of t = 6
