How many solutions do the following equations have?

8x + 10 = 8x -7

1 answer

The equation 8x + 10 = 8x - 7 doesn't have any solutions.

To see why, let's try to solve it:

8x + 10 = 8x - 7
Subtracting 8x from both sides:
10 = -7

Since 10 is not equal to -7, there is no solution to this equation.
