Pre-Calculus - Solve a system of linear equations using substitution

In this video we take on solving a system of linear equations in two variables using the substitution method. This is one of the first methods you usually learn for solving a system and its pretty strait forward. Remember that you will go through the substitute and solve process twice, once for each variable.

this helped me out so much, thanks

[@user-pp3vy4xu5g]

hii, were already in trigonometry but im still having a problem with substitution,, can i ask how can you determine where to transpose things? thank u!

[@letorivers9486]

thanks a lot i needed help on this C:

[@vina6036]

Can you do a long devision video please

[@MySecretMathTutor]

Do you mean long division of polynomials, or just long division of numbers?

[@vina6036]

MySecretMathTutor polynomials please

[@MySecretMathTutor]

Ah you are in luck. I already have a few different videos on the subject.
