Subtract each remember 4-- -6= 10
Mikayla subtracted 4 from both sides in the beginning when she should've added it to both sides to cancel it out on the right. the correct answer should actually be x=1
Let C be the number of cats and B be the number of birds.
Each cat has 4 legs while each bird has 2 legs. Thus,
4C + 2B = 22
2B = 22 - 4C
Each cat and each bird has 2 eyes
2C + 2B = 16
Substituting 2B
2C + 22 - 4C = 16
2C = 6
C = 3
2B = 22 - 4(3)
B = 5
2 cats and 5 birds

Answer:
33×33+33-33÷0=infinity
33×33=1089
33-33=0
Taking L.H.S
=33×33+(33-33)÷0
=1089+0÷0
=1089÷0
=infinity
L.H.S=R.H.S
