Answer 2

To solve the equation, follow these steps:

1. Combine like terms on each side of the equation.
2. Isolate the variable (x) on one side of the equation by performing inverse operations.

Let's solve the equation step-by-step:

Given equation: 430 - x = 170 - 40

Step 1: Combine like terms On the right side, 170 - 40 simplifies to 130:

430 - x = 130

Step 2: Isolate the variable (x) To isolate x, we need to move -x to the other side of the equation by adding x to both sides:

430 - x + x = 130 + x

The -x and +x on the left side cancel each other out, leaving:

430 = 130 + x

Next, to isolate x, we need to move 130 to the other side by subtracting 130 from both sides:

430 - 130 = x

Now, calculate the result:

x = 300

Therefore, the solution to the equation is x = 300.
