I just started taking geometry and discrete math and we're just learning 2d matrices. Here is a problem I can't figure out: 1) My wife and I are 6 years apart in age. If you double the sum of our ages and add 50, you get the same number as when you add 25 to the sum of our ages and double it. How old am I? Ok so let x - be the age of him, and y be his wifes age We can assume that he is older then his wife so x - y = 6 Then 2(x + y) + 50 = 2(x + y + 25) Here's is where I'm confused Can someone tell me the next few steps into setting up this problem.
