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.
Well Georgemichels, it looks like you are going to be banned....
It’s not likely anyone here will miss you, but I know there are at least two who will be happy to see you go.
