age word problems as a system of two equations (KristaKingMath)

► My Algebra 2 course: https://www.kristakingmath.com/algebr...

In this video we'll learn how to solve age word problems using systems of linear equations, or simultaneous equations. Specifically, we know that a man is older than his son, and that the ratio between their ages will be different in some years from now. We need to find their ages today.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
