Answer 3

To solve the equation 15x - x = 140, you need to combine like terms and then isolate the variable x. Here's the step-by-step solution:

1. Combine like terms: 15x - x = 14x (Subtract x from 15x to get 14x on the left side of the equation.)

2. Now the equation becomes: 14x = 140

3. Isolate the variable x: To isolate x, divide both sides of the equation by 14: 14x / 14 = 140 / 14 x = 10

So, the solution to the equation is x = 10.
