Answer:

Step-by-step explanation:

23x+22y=89..........(1)              now add eq 3and eq4

22x+23y=91.........(2)                ∴x+y=4+ x-y=2            

                                                  ∴2x=6

by add eq 1 and 2                     ∴x=3    ,put x=3 in eq3

23x+22y=89                                ∴3+y=4

+22x+23y=91                               ∴y=1

45x+45y=180                     ∴x=3 and y =1

45(x+y)=180

x+y=180/45

x+y=4.....(3)

now subtract eq2-eq1

∴22x+23y=91

  • -23x+22y=89

x+y=2..........(4)
