Answer 2

Let's solve this step by step:

1. Start with the first equation: 432 ÷ 18 = 360 ÷ 18 + a ÷ 18

   Simplify both sides of the equation: 24 = 20 + a ÷ 18

   Now, isolate 'a' by subtracting 20 from both sides: 24 - 20 = a ÷ 18 4 = a ÷ 18

   To find 'a', multiply both sides by 18: 4 * 18 = a a = 72

2. Move on to the second equation: b ÷ 19 + 380 ÷ 19 = 475 ÷ 19

   Simplify both sides of the equation: (b ÷ 19) + 20 = 25

   Now, isolate 'b' by subtracting 20 from both sides: b ÷ 19 = 25 - 20 b ÷ 19 = 5

   To find 'b', multiply both sides by 19: b = 5 * 19 b = 95

So, the solutions are: a = 72 b = 95
