7b = 63 Divide both sides by 7:- b = 9
a=7 b=9 ab=? ab is the multiplication of a & b there fore the value of ab=7*9=63
The asterisk * A * B = the product of A and B 2 * 7 = 14
10a + b = 7(a + b) 10a + b = 7a + 7b 3a = 6b a = 2b (2,1), (4,2), (6,3), and (8,4) meet these requirements. So the numbers that are solutions are 21, 42, 63, and 84.
