Algebra 27 - Solving Problems with Linear Equations

How do we create linear equations to solve real-world problems? This video explains the process.

you made linear equations easier for me.

So, at the end, we have left over from that wire. :D

Another excellent video.  The only thing that I am not totally comfortable with is the use of decimals with inches on the third example.  I think if a person tried to actually cut a 10 inch length at 5.4 inches, they would be confused as to where to cut.  A suggestion would have been to use centimeters rather than inches for the gold string.

After many searches, i found the batter explanation here.

Brilliant, as always. Q: How many videos would it take to get to understanding the mathematical proof that time slows down when we approach the speed of light?

@ Clinton Sam ; must be 50 because he was speaking about total age. He was converting $ unit to age unit first. While your solution is not wrong, it uses different units at initial equation. Your equation is solving the problem in one equation while the video used 2 equations with the first unexplained one being the unit conversion from $ to age.

You know that an easier way of simplifying is just moving the term to the other side, while changing it's + or - sign (or it's position in the numerator/denominator if fractions are considered). All of this long process of subtracting x from z to get 0 would be omitted.

The title of this video should be "Solving Problems with *Literal* Equations"

I only wish my brain could be rewired to work this way, its so frustrating you know?
