Answer 3

It looks like you have three equations with variables y, b, and a. Let's solve each equation step by step:

1. 45×2×у = 900 To solve for y, divide both sides of the equation by (45 * 2): 45 * 2 * y = 900 (45 * 2 * y) / (45 * 2) = 900 / (45 * 2) y = 900 / 90 y = 10

2. 45×2 + b = 900 To solve for b, subtract 45 * 2 from both sides of the equation: 45 * 2 + b - 45 * 2 = 900 - 45 * 2 b = 900 - 90 b = 810

3. a - 45×2 = 900 To solve for a, add 45 * 2 to both sides of the equation: a - 45 * 2 + 45 * 2 = 900 + 45 * 2 a = 900 + 90 a = 990

So, the solutions to the three equations are: y = 10 b = 810 a = 990
