Answer 2

To solve the equation X-15=2x, we want to find the value of X that satisfies the equation. Here's the step-by-step process:

Step 1: Combine like terms Add 15 to both sides of the equation to get all the X terms on one side of the equation and the constant terms on the other side.

X - 15 + 15 = 2x + 15

This simplifies to:

X = 2x + 15

Step 2: Isolate the X term To isolate the X term on one side, we need to get rid of the 2x on the right side of the equation. We can do this by subtracting 2x from both sides.

X - 2x = 2x + 15 - 2x

This simplifies to:

-X = 15

Step 3: Solve for X To solve for X, multiply both sides of the equation by -1 to get rid of the negative sign in front of X.

(-1) * (-X) = (-1) * 15

This simplifies to:

X = -15

The solution to the equation is X = -15.
