Answer 3

To solve the equation 40 - x = 19, you need to isolate the variable x on one side of the equation. Here's how you can do it:

1. Subtract 40 from both sides of the equation to move the constant term to the other side:

40 - x - 40 = 19 - 40

This simplifies to:

-x = -21

2. Now, to solve for x, multiply both sides by -1 to get rid of the negative sign in front of x:

(-1) * (-x) = (-1) * (-21)

This gives us:

x = 21

So the solution to the equation is x = 21.
