Answer 2

To solve the equation 7-x=18, you need to isolate the variable x on one side of the equation. Here's the step-by-step solution:

1. Start with the original equation: 7 - x = 18

2. To isolate x, we want to get rid of the constant term (7) on the left side. We can do that by subtracting 7 from both sides of the equation:

   7 - x - 7 = 18 - 7

3. Simplify both sides:

   -x = 11

4. Now, we have -x = 11. To solve for x, we need to get rid of the coefficient -1 in front of x. We can do this by multiplying both sides by -1:

   (-1) * (-x) = (-1) * 11

5. Simplify both sides:

   x = -11

So the solution to the equation is x = -11.
