Question

Find , and r for the following pairs of
integers a and b satisfying a = bq+r.
1. a = 13, b = 3 4: a = -32, b = -12
2. a = 18, 6= 4 5. a = -31, 6=7
3. a=21, 6 -4​

Answer 1

Answer:

a=13 b=3

Step-by-step explanation:

13=3q+r

a=18 b=4

18=4q+r

solving 13=3q+r and 18=4q+r

we get q=5 and r=-2
