Answer 3

To solve the equation 89 - x = 42, you need to isolate the variable x on one side of the equation. Here's the step-by-step solution:

1. Get rid of the constant term (42) on the right side by subtracting it from both sides of the equation: 89 - x - 42 = 42 - 42

Simplify the equation: 47 - x = 0

2. Now, we want to isolate the variable x on one side. To do that, we need to get rid of the constant term on the left side (47). Since it is being subtracted from x, we can eliminate it by adding 47 to both sides of the equation:

   47 - x + 47 = 0 + 47

Simplify the equation: 47 + 47 - x = 47

3. Now, we have:

   94 - x = 47

4. Finally, isolate x by subtracting 94 from both sides of the equation:

   94 - x - 94 = 47 - 94

Simplify the equation: -x = -47

5. To find the value of x, multiply both sides by -1:

   -1 * -x = -1 * -47

   x = 47

So, the solution to the equation is x = 47.
