x = -18

thx

To solve the equation 6x - 7x = 18, you need to combine the like terms on the left side of the equation.

First, notice that the two terms on the left side both have the variable x, so you can combine them.

6x - 7x simplifies to -x.

Now, you have the equation -x = 18.

To solve for x, you need to isolate the variable x.

To do this, you can multiply both sides of the equation by -1 to get rid of the negative sign in front of x.

This gives you x = (-1) * 18, which simplifies to x = -18.

So, the solution to the equation 6x - 7x = 18 is x = -18.
