How to simplify 3x - x = 10

Answer 1

To simplify the equation 3x - x = 10, we can combine like terms on the left side of the equation:

3x - x = 10
(3-1)x = 10
2x = 10

Now, to solve for x, we divide both sides of the equation by 2:

2x/2 = 10/2
x = 5

Therefore, the solution to the equation 3x - x = 10 is x = 5.
