Answer 2

It appears there might be a mistake in the equation you provided. Let's break it down step by step:

(170 - x) + 80 = 140

First, you can simplify the equation by combining like terms:

170 - x + 80 = 140

Now, subtract 80 from both sides of the equation:

170 - x = 140 - 80

This simplifies to:

170 - x = 60

To solve for 'x,' you can isolate it on one side of the equation. To do this, you can subtract 170 from both sides:

170 - x - 170 = 60 - 170

This simplifies to:

-x = -110

Now, to solve for 'x,' you can multiply both sides by -1 to make 'x' positive:

(-1) * (-x) = (-1) * (-110)

This gives you:

x = 110

So, the solution to the equation is x = 110.
