▶ Question : (3x-2y=5 ; 5x-y=3) Solve by substitution method



▶ Explanation :-



=> 3x - 2y = 5 -------- ( 1 )


=> 5x - y = 3 --------- ( 2 )


=> 5x - y = 3


=> 5x = 3 + y


=> x = 3 + y / 5 -------- ( 3 )



Substituting eq ( 3 ) in eq ( 1 )



=> 3 ( 3 + y / 5 ) - 2y = 5


=> 9 + 3y / 5 - 2y = 5


=> 9 + 3y - 10y / 5 = 5


=> 9 - 7y = 5 × 5


=> 9 - 7y = 25


=> - 7y = 16


=> y = - 16 / 7



Substituting value of y in eq ( 3 )


=> x = 3 + ( - 16 / 7 ) / 5


=> x = 3 - 16 / 7 /5


=> x = 21 - 16 / 35


=> x = 5 / 35


=> x = 1 / 7
