Question

7x-2y=3;22x-3y=16 cross multiplication​

Answer 1

Answer:

7x – 2y – 3 = 0 …(1)

22x – 3y – 16 = 0 …(2)

From equation (1): a1 = 7, b1 = – 2 and c1 = – 3 From equation (2): a2 = 22, b2 = – 3 and c2 = –16

Using cross multiplication method:

32-9/x=-66+112/y=-21+44/1

=>23/x=46/y=23/1

=>23/x=23/1

=>x=23/23

=1

and,

=>46/y=23/1

=>y=23/46

=2

•°• x=1 , y=2
