Answer:
=−6
Step-by-step explanation:
Answer:
8x - 3y = 12 _______( 1 )
5x = 2y + 7 _______( 2 )
On further solving ( 2 ), we get
5x - 2y = 7 _______( 3 )
Multiply ( 1 ) by 2
16x - 6y = 24 _______( 4 )
Multiply ( 3 ) by 3
15x - 6y = 21 _________( 5 )
Subtract ( 4 ) and ( 5 )
( 16x - 6y ) - ( 15x - 6y ) = 24 - 21
16x - 6y - 15x + 6y = 3
Put this in ( 2 )
5 ( 3 ) = 2y + 7
15 = 2y + 7
2y = 15 - 7
2y = 8
y = 8 / 2
