Solve a System by Graphing, Substitution, Elimination

To solve a system of equations we can graph, solve by substitution or by elimination. In this video we will cover all three.

You're my go-to math teacher. Your videos have made summer school easier, especially because I'm learning completely new material at such a fast pace. I really need this, thank you.

[jsmoss]

You explain this a lot better than my professor, she just right notes and expects you to figure out each step on your own

[Daviddrt.]

Thank you I have a test on all three in 12 hours this has really helped.

I just found this on the algorithm under “watch again” and I realized I forgot to comment! You saved my butt in eighth grade, and I got accepted into a high school thanks to my high math grade 😁
Couldn’t have done it without you, thank you so much.

Excellent video! I'm relieved you decided put all three methods in one video.

I know i am late to the party, but thank you so much! If i don't pass this test, i'm going to loose out on High school credits, and i now fell 10x more confident in myself and my ability to do this!🙂

At 4:30 the graph solution given is not correct. The correct solution should have been (-2, -5). The graph was crooked.

Thank you so much for this compilation! I have a test on all of these in 2 days.

[gravethedawnx]

you make everything so easy can you please make videos on the harder things like quadratics and stuff

[Buffering]

You just saved my grade thank you so much.😁

[hamidzaidi]

I don’t understand the way you’ve shown it why adding or subtracting in the first step of the equations

[Golidddking]

I am not understanding is there other way simpler

[zesrdtfyguhiasdasfv]

i think the first one is wrong because i got (-2, --5, ) i am using graph paper and i dont see the solution. Good video just a heads up

[rachelrose]

wow this helped a lot i have a test pretty soon good video!

[bckvbre]

why did 12y+(-12) make it x=2 i dont get it pls someone understand

[ronaldjorgensen]

graph 1/4 pi in abstraction @ 45 degree rms sine wave as example also launch measure probe from 0/0 to intersect peak power inertia path of first 3 harmonicsmy pen goes dry trying

[Keepyourthoughtspositive]

I found graphing so confusing since you were a bit fast found it even shed to register anything 🙁🙁😩😩

[mikesmith]

Sir, are you by any chance taking students who've finished school? 😂😂

[Chickenfireball-pjgl]

3 hours of studying fit into 13 minutes

[nsporational_]

at 6:43 why does it -2x+4, and not 2x - 4 ?? someone pls expain
