# If AB × B = 9B, then A = _________, B = _________.

**Solution:**

If AB × B = 9B then B can be 1 or 6.

If B = 1 then A = 9 because 91 × 1 = 91

However there is another possibility and that is

If B = 6 and A = 1 then we have 16 × 6 = 96

Hence

If AB × B = 9B, then A = 1 or 9, B = 6 or 1 respectively

**✦ Try This: **If AB × B = 7B, then A = _________, B = _________.

B can take the value of 5 or 6.

But if B = 6 then 76 is not possible

However if B = 5 then 75 is possible because 15 × 5 = 75

Hence A = 1 and B = 5
