Answer 2

А) To solve the equation 7.32 + x = -3.18, you need to isolate the variable x on one side of the equation. Here's how you can do it:

1. Start by subtracting 7.32 from both sides of the equation to move the 7.32 to the other side: 7.32 + x - 7.32 = -3.18 - 7.32

2. Simplify both sides of the equation: x = -3.18 - 7.32

3. Calculate the right-hand side: x = -10.50

So, the solution to the equation is x = -10.50.

Б) To solve the equation y - 4 5/12 = -2 7/15, you can follow these steps:

1. Start by adding 4 5/12 to both sides of the equation to isolate y on the left side: y - 4 5/12 + 4 5/12 = -2 7/15 + 4 5/12

2. Simplify both sides of the equation: y = -2 7/15 + 4 5/12

3. Find a common denominator for the fractions on the right side. The common denominator for 15 and 12 is 60: y = (-2 * 4) 60/15 + (5 * 5) 60/12

4. Perform the multiplication and addition: y = (-8) 60/15 + (25) 60/12

5. Simplify each fraction: y = -32 60/15 + 300 60/12

6. Reduce the fractions to their simplest form: y = -128/3 + 150/1

7. Convert -128/3 to a fraction with a common denominator of 3: y = -128/3 + 450/3

8. Now, add the fractions: y = (450 - 128)/3

9. Calculate the numerator: y = 322/3

So, the solution to the equation is y = 322/3.
