+1904 What two numbers when added together equals 3, subtracted together equals -1, multiplied together equals 2, and divided together equals \(0.5\)? Please show how you got to your answer by subtition, subtraction, and graphing.
+118687 Hi Gibsonj338, 
I am sure that you already know the answer is 2 and 1. I did it with simultaneous equations which is how you would usually do it too.
That is a=1 and b=2
a+b=3
a-b=-1
ab=2
a/b=1/2
Am I mising something here?
+129928 a + b = 3
a - b = -1 add these equations
2a = 2 divide both sides by 2
a = 1
So....if ab = 2, then.....
(1)b = 2 so b = 2
And a/b = 1/2
Here's a graph of all the equations and their solution at the intersection point (1,2)......I have substituted x, y for a, b
