Answer 3

To solve the equation "620 - X = 80," follow these steps:

Step 1: Move the constant term to the other side of the equation by adding 80 to both sides: 620 - X + 80 = 80 + 80 Simplifying: 620 - X + 80 = 700

Step 2: Combine like terms on the left side of the equation: 620 + 80 - X = 700 700 - X = 700

Step 3: Isolate the variable term by moving the constant term to the other side of the equation: 700 - 700 = X 0 = X

So the solution for X is X = 0.

Now let's solve the second equation "x + 120 = 400":

Step 1: Move the constant term to the other side of the equation by subtracting 120 from both sides: x + 120 - 120 = 400 - 120 Simplifying: x = 280

So the solution for x is x = 280.

The solutions for the two equations are: X = 0 x = 280
