Answer 3

Let's solve the equations one by one:

1. 2x = 18 - x

To solve this equation, we'll move all the terms involving x to one side of the equation and the constant terms to the other side:

2x + x = 18

Combining like terms:

3x = 18

Now, isolate x by dividing both sides of the equation by 3:

x = 18/3

Simplifying:

x = 6

So the solution to the equation is x = 6.

2. 7x + 230 - 2x

To simplify this expression, we'll combine like terms:

7x - 2x + 230

Combining the x terms:

5x + 230

So the simplified expression is 5x + 230.
