Answer 3

It looks like you're trying to solve an equation, but there are some issues with the equation you've provided. Let's correct it and solve for 'x':

The equation you provided appears to be written incorrectly. To correct it, let's start with the equation:

15 * (x + 20) - 30 = 12x

Now, let's solve for 'x':

1. Distribute the 15 on the left side of the equation: 15x + 300 - 30 = 12x

2. Combine like terms: 15x - 30 = 12x

3. To isolate 'x', you can subtract 12x from both sides of the equation to get all the 'x' terms on one side: 15x - 12x - 30 = 12x - 12x

This simplifies to: 3x - 30 = 0

4. Add 30 to both sides of the equation to isolate '3x': 3x - 30 + 30 = 0 + 30

This simplifies to: 3x = 30

5. Finally, divide both sides by 3 to solve for 'x': (3x)/3 = 30/3

This simplifies to: x = 10

So, the solution to the equation is x = 10.
