Answer 2

It looks like you've provided three equations. Let's solve each of them step by step:

1. $X \times (78 - 75) = 27$ Simplify inside the parentheses: $78 - 75 = 3$ Now the equation becomes: $X \times 3 = 27$ Divide both sides by 3: $X = 9$

2. $(47 \times X) \div 5 = 10$ Multiply 47 by X: $47X \div 5 = 10$ Multiply both sides by 5: $47X = 50$ Divide both sides by 47: $X = \frac{50}{47}$

3. $31 - x = 4 \times 3$ Multiply 4 by 3: $31 - x = 12$ Subtract 31 from both sides: $-x = -19$ Multiply both sides by -1: $x = 19$

So, the solutions are:

1. $X = 9$
2. $X \approx 1.0638$ (rounded to four decimal places)
3. $x = 19$
