Answer 3

To solve the equations, let's break them down step by step:

Equation 1: Y + 5 3/4 = 12 7/12

First, let's convert the mixed numbers into improper fractions: 12 7/12 = (12 * 12 + 7) / 12 = 151 / 12

Now, let's subtract 5 3/4 from both sides of the equation: Y + 5 3/4 - 5 3/4 = 151/12 - 5 3/4 Y = 151/12 - 23/4

To add or subtract fractions, we need to find a common denominator. In this case, the common denominator is 12. Y = (151 - 69) / 12 Y = 82/12 Simplifying the fraction, we get: Y = 41/6

So the solution to Equation 1 is Y = 41/6.

Equation 2: 3 1/4 - x = 2 7/24

Let's convert the mixed numbers into improper fractions: 3 1/4 = (3 * 4 + 1) / 4 = 13/4 2 7/24 = (2 * 24 + 7) / 24 = 55/24

Now, let's subtract 13/4 from both sides of the equation: 3 1/4 - 13/4 - x = 55/24 - 13/4

• x = 55/24 - 13/4

To subtract fractions, we need to find a common denominator. In this case, the common denominator is 24.

• x = (55 - 78) / 24
• x = -23/24

To solve for x, we need to multiply both sides by -1: x = 23/24

So the solution to Equation 2 is x = 23/24.
