Real numbers a and b satisfy

a + ab = 250

a - ab = -240

Enter all possible values of a, separated by commas.

To find the possible values of a, we can solve the given system of equations:

a + ab = 250 ...(1)
a - ab = -240 ...(2)

We can use the method of elimination to solve this system. Adding equations (1) and (2) eliminates the term 'ab':  mymilestonecard

(a + ab) + (a - ab) = 250 + (-240)
2a = 10
a = 5

Substituting the value of a back into equation (1):

5 + 5b = 250
5b = 245
b = 49

Therefore, the solution is a = 5 and b = 49. There is only one possible value for 'a', which is 5, and one possible value for 'b', which is 49.
