Answer 2

Solving the Equations

Let's solve the given equations step by step:

1) 22x = 66: To solve this equation, we need to isolate the variable x. We can do this by dividing both sides of the equation by 22: ``` 22x = 66 x = 66/22 x = 3 ``` Therefore, the solution to the equation 22x = 66 is x = 3.

2) -x = 4.25: To solve this equation, we need to isolate the variable x. We can do this by multiplying both sides of the equation by -1: ``` -x = 4.25 x = -4.25 ``` Therefore, the solution to the equation -x = 4.25 is x = -4.25.

3) 7x = 0: To solve this equation, we need to isolate the variable x. We can do this by dividing both sides of the equation by 7: ``` 7x = 0 x = 0/7 x = 0 ``` Therefore, the solution to the equation 7x = 0 is x = 0.

4) 4 - x = 0: To solve this equation, we need to isolate the variable x. We can do this by subtracting 4 from both sides of the equation: ``` 4 - x = 0 -x = -4 x = 4 ``` Therefore, the solution to the equation 4 - x = 0 is x = 4.

5) 2x - 5 = 5: To solve this equation, we need to isolate the variable x. We can do this by adding 5 to both sides of the equation: ``` 2x - 5 = 5 2x = 5 + 5 2x = 10 x = 10/2 x = 5 ``` Therefore, the solution to the equation 2x - 5 = 5 is x = 5.

Summary of Solutions:

The solutions to the given equations are as follows: 1) 22x = 66: x = 3 2) -x = 4.25: x = -4.25 3) 7x = 0: x = 0 4) 4 - x = 0: x = 4 5) 2x - 5 = 5: x = 5
