How to solve a word problem with systems of equations
👉Learn how to solve a system of linear equations from a word problem. A system of equations is a set of more than one equations which are to be solved simultaneously. A word problem is a real world simulation of a mathematical concept. The solution to a system of equation is the set of values of the variables that satisfies all the equations in the system.
To solve a system of equation word problems, we first define the variables and then extract the equations from the word problems. We can then solve the system using graphing, elimination, or substitution methods.

It’s much harder to pay complete attention to what you’re writing while trying to teach, that’s why teachers make so many mistakes writing on the board, that’s what the smart kids are for.

Thankyou for this video. I'm in a college class that is asynchronous and online. Trying to learn this without a teacher explaining it makes no sense. I really appreciate the explanation.
I'm salty. This is a great explanation, but every time I find problems like this, I'm missing both the number of each item used & the total number of all the items. But I wind up expected to solve for both. i.e. Total Monetary value = known Value of individual objects = known number of each object = unknown total number of all objects = unknown.
OMG you've been saving my life.
i always watch your videos and they help out so much!
Thank you so much. Your video has helped me so much in math class
Thanks Teacher, mis estudiantes de Cali Colombia agradecen su video.
I have a test in a few hours And this helped me more than my teacher has
you really helped me so much you deserve more credit
you did a great help reviewing me for our quiz tomorrow. thanks a lot!
@Brian McLogan how will I get an answer if I don't start with the numbers for how many of each??
Thank you sir I have a problem just like this but our teacher uses a box with categories to the left side then cost, amount, and total going on top as titles for the rows then we just fill them in it makes it easier to understand for us but I had forgotten how to do it but this way was clear too so thank you 👍🏽
Thanks, this was way easier than how my professor explained it
thank you so much, this helped me so much. :)

How do you know if you need to use substitution or elimination

you can always use either, usually substitution is easier if one of the variables does not have a coefficient

Pricilla sells stuffed animals at a local craft show. She charges 13 dollars for the small ones , and 12 for the large. She sold 350 dollars worth of animals after the show. She noticed that she sold 27 stuffed animals. How many were small, and how many were large?

What happened at 4:52 ? That didnt seem to be explained. It just seemed to jump straight to x = 26. " you just combine like terms" = x
Genius
Where did 324 come from? Sorry I'm confused
But arent we suppose to use the y=mx+b rule? Why did you make it y=27-x instead of y=-x+27?
