Answer 3

To solve these equations, let's go through each one step by step:

1. X/6 = 5 To isolate X, we can multiply both sides of the equation by 6: X = 5 * 6 X = 30

2. X + 81 = 99 To isolate X, we can subtract 81 from both sides of the equation: X = 99 - 81 X = 18

3. X - 42 = 48 To isolate X, we can add 42 to both sides of the equation: X = 48 + 42 X = 90

4. 63/X = 21 To isolate X, we can multiply both sides of the equation by X: 63 = 21 * X Divide both sides by 21: X = 63/21 X = 3

So the solutions for each equation are:

1. X = 30
2. X = 18
3. X = 90
4. X = 3
