solve elimination method explained
​

Answer 1

Answer:

see as A1/A2 = not b1/b2 therfore it has a unique solution

Step-by-step explanation:

x-4y=5..........(I)

3x+y=2.........(ii)

now multiply (ii) by 4 and add (I) and (ii)

x-4y=5

+12x+4y=2

=13x = 7

therefore x=7/13

now substitute this value in eq (I)

7/13-4y=5

7-52y=5*13

52y=65-7

y=58/52=29/26
