Answer 2

Let's solve the equations one by one:

1. (x + 3) * 2 = 18

Expand the expression: 2x + 6 = 18

Subtract 6 from both sides: 2x = 12

Divide both sides by 2: x = 6

Therefore, the solution to the equation is x = 6.

2. (x - 7) * 4 = 64

Expand the expression: 4x - 28 = 64

Add 28 to both sides: 4x = 92

Divide both sides by 4: x = 23

Therefore, the solution to the equation is x = 23.

3. (x - 9) / 2 + 25

There seems to be a missing equal sign in this equation. If you meant to write an equation, please provide the equal sign and the value the expression should equal to.

4. (x + 5) / 7 = 8

Multiply both sides by 7: x + 5 = 56

Subtract 5 from both sides: x = 51

Therefore, the solution to the equation is x = 51.

5. 7x + 18 = 60

Subtract 18 from both sides: 7x = 42

Divide both sides by 7: x = 6

Therefore, the solution to the equation is x = 6.

6. (x - 15) / 3 = 11

Multiply both sides by 3: x - 15 = 33

Add 15 to both sides: x = 48

Therefore, the solution to the equation is x = 48.
