No solution because, 15 is not equal to 0. You can cancel out both -x's and it leaves u with 15=0 and that's not true.

You need to get the variable on only one side of the equation (for this problem, add x to both sides). From the looks of it, you probably copied the problem wrong onto the computer because you have an impossible answer. Double check that.

This problem is impossible! If you wrote it right, you'll end up with 15=0!

15-x=-x
add x on both sides
15-x=-x
15+x=+X
x=15
not sure if this is right
