Answer 2

To solve the equation 900 - x = 129 × 4, follow these steps:

Step 1: Simplify the right side of the equation by performing the multiplication: 129 × 4 = 516

Step 2: Now, the equation becomes: 900 - x = 516

Step 3: To isolate x on one side of the equation, you need to move 900 to the other side. Since it's currently being subtracted, you will add 900 to both sides of the equation: 900 - x + 900 = 516 + 900

Step 4: Simplify both sides of the equation: 900 + 900 - x = 1416

Step 5: Combine like terms: 1800 - x = 1416

Step 6: To solve for x, isolate it on one side of the equation. Since x is being subtracted from 1800, you will add x to both sides: 1800 - x + x = 1416 + x

Step 7: Simplify both sides of the equation: 1800 = 1416 + x

Step 8: Finally, isolate x by subtracting 1416 from both sides: 1800 - 1416 = x

Step 9: Calculate the value of x: x = 384

So, the solution to the equation is x = 384.
