How many real number Solutions does the equation have 0 equals 5x + 2x - 12

To determine the number of real number solutions for the equation 0 = 5x + 2x - 12, we need to first simplify the equation:

0 = 5x + 2x - 12
0 = 7x - 12
7x = 12

Now, to solve for x, we divide both sides of the equation by 7:

x = 12/7

Therefore, there is only one real number solution for the equation 0 = 5x + 2x - 12.
