Answer :
b + c = 52.....b = 52 - c
2b + 4c = 138
2b + 4c = 138
2(52 - c) + 4c = 138
104 - 2c + 4c = 138
2c = 138 - 104
2c = 34
c = 17
b + c = 52
b + 17 = 52
b = 52 - 17
b = 35
so there is 35 birds (b) and 17 cats (c)
2b + 4c = 138
2b + 4c = 138
2(52 - c) + 4c = 138
104 - 2c + 4c = 138
2c = 138 - 104
2c = 34
c = 17
b + c = 52
b + 17 = 52
b = 52 - 17
b = 35
so there is 35 birds (b) and 17 cats (c)
