16 - Solving Systems of Equations by Substitution, Part 1 (Simultaneous Equations)

Learn how to solve a set of simultaneous equations by the method of substitution. First, we will isolate one of the variables and then substitute it into the other equation to find the answer to one of the variables.

After this we can find the remaining variable of the system by performing another substitution operation.

[mthobisizondi]

Sir do you have any lessons about subject of the formula and by the way you the best thanks for the lessons god bless you

[princemike]

Wow sir your teaching is very interesting

Hello there can you explain to me one of the reasons why simultaneous equations are used within science possibly I'm thinking it might help me to understand it more as to why there are two processes approach to solving. The Elimination and substitution

sir pls how do i solve this equation it has been giving me a hard time solving but i don't know if am correct 2x+y=11, 7x-4=14 i actually solved it but am not sure if am correct sir

For the 3rd example, what if they do not have the same value. Like 3x-y=5 and 2x-y=-3, what would be the steps for that?

Really MY IDEA IT WAS BETTER TO MAKE ADDING BOTH OF THEM LIKE X+Y AND X-Y=4. SO IT WOULD BE EASY TO MAKE THE SOLUTION
