Answer 3

Solving the Equation

To solve the equation 800 - (90x + 17) = 423, we can follow these steps:

1. Combine Like Terms: Combine the terms on the left side of the equation. 2. Isolate the Variable: Isolate the variable term to solve for its value.

Step 1: Combine Like Terms

We start by combining the terms on the left side of the equation:

800 - (90x + 17) = 423

800 - 90x - 17 = 423

783 - 90x = 423

Step 2: Isolate the Variable

Next, we isolate the variable term to solve for its value:

783 - 90x = 423

Subtract 783 from both sides:

-90x = 423 - 783

-90x = -360

Now, divide both sides by -90 to solve for x:

x = -360 / -90

x = 4

Solution

The solution to the equation 800 - (90x + 17) = 423 is x = 4.
