Answer 3

Solving the Equation

To solve the equation 437 - (x - 83) = 20, we can follow these steps:

1. Distribute the Negative Sign: Distribute the negative sign inside the parentheses. 2. Combine Like Terms: Combine the constants and the x term. 3. Isolate the Variable: Isolate the variable x by performing the necessary operations to solve for x.

Let's solve the equation step by step.

1. Distribute the Negative Sign: - The equation 437 - (x - 83) = 20 becomes 437 - x + 83 = 20 after distributing the negative sign inside the parentheses.

2. Combine Like Terms: - Combine the constants: 437 + 83 = 520. - The equation becomes 520 - x = 20.

3. Isolate the Variable: - To isolate x, we can subtract 520 from both sides of the equation. - This gives us -x = 20 - 520, which simplifies to -x = -500. - Finally, multiplying both sides by -1 gives us x = 500.

So, the solution to the equation 437 - (x - 83) = 20 is x = 500.
