We can solve for a by adding the two given equations:
a + ab + a - ab = 250 - 240
2a = 10
a = 5
Now we can substitute back into one of the given equations to solve for b:
5 + 5b = 250
5b = 245
b = 49
So the only possible values for a and b that satisfy the given equations are:
a = 5, b = 49
a + ab + a - ab = 250 - 240
2a = 10
a = 5
Now we can substitute back into one of the given equations to solve for b:
5 + 5b = 250
5b = 245
b = 49
So the only possible values for a and b that satisfy the given equations are:
a = 5, b = 49
