Solving a system of equations by using the substitution method

👉Learn how to solve a system of equations by substitution. To solve a system of equations means to obtain a common values of the variables that makes the each of the equation in the system true. To solve a system of equations by substitution, we solve for one of the variables in one of the equations and then substitute for the variable in the other equation and then solve for the other variable. Next we plug in the obtained value of the other variable into the equation for the initial variable we solved for to obtain the value of the variable.

The value of the two variables obtained is the solution to the system of equations.

You my man are the real mathemetician! Thank you

[trent]

Thank you so very much for taking the time out to upload these videos for people who needs a little push in the right direction, it means a lot to us all! 😊

[joselyngarcia]

Thank you so much! You make these topics so easy to understand. I have to do so much self studying because my algebra teacher isn’t very good at explaining. Your videos are really helping me out!😭

[annakrahn]

I watched a few different videos on substitution and your video is the only one that explained it to me. Thank you so much!!!

[celinaestrada]

This helped me so much! Thank you! 🙂👍🏻 work appreciated.

[sebastianmontoya]

Been learning this for weeks my whole class failed the test on this because my teacher is horrible

[IEverything-U]

Thank you much! I love this way! I have been trying to figure out a problem for look at this video and it finally clicked!

[emaankazi]

Omg thank you this made so much sense! I've been working on this for a week and still couldn't understand until i found your channel! Just subscribed!
Thanks again!👌🏼😁

[morgantaylor]

Thank you so much! I still watch you videos from many many years ago and they still help me! So thank

[mustafemire]

understood
Tank so much
my teacher. 100%

[hattiemerryman]

You know how many tests this guy has helped me study for Thankyou sm!!

[gab.byyyyyyyy]

I love you!! Studying right before a test is stressful. Ahhhh!
I'll give yall an update if I pass...

[buhnana]

What should you do if both x variables have a coefficient of one

[telltruthgoddance]

He makes it look so easy! It’s great! I got it right away! The hint helps a lot!!!!

[GraceDumplings]

Thank you for this, I have to finish a test tomorrow and I always solve for y in the standard form which always gives me a fraction. I was so stressed out but now I know u can solve for x in the standard form an still get the same anser. Thank you so much you really helped me

[Hammxd-uqxx]

I am studying for my exams they r after 2 weeks im studying for it thank u

[KuyaWoods]

you are better teacher than my teacher i dont understand him at all

[ABCDEFGH]

i was so confused by you, I would rather go direct
take 2nd equation x + 2y = 10, then x = 10-2y, apply to equation (1), then 4(10-2y) + 3y = 10, then 40-8y+3y=10, then 40-5y=10, then -5y=10-40= -30, so -5y=-30, -y=-6, y=6, apply y=6 to equation (2), x+12=10, x=10-12, x= -2

[steliostelio]

Hi mr brian . I wanted to wright you on twitter but you have turned messages off. I have a question about factorials . For example : (m-n)!=m!-n!

[littlebigcomrade]

I help need with substitution when there are fractional exponents.

For example:

3y^-2 + y^-1 + 4 = 0
