5:19 The other way... it is "(8, 2)", because you should have your x solutions first then the y solutions, so "(x, y)" as x = 2, and y = 8; it should be "(2, 8)"

This helped so much! I was great at doing this with whole numbers, fractions have never been my strong suit!

i am 9 learning this stuff and Ive looked the like a million videos and your the only one I understand

[graynewsome]

Thank you!!! I started my unit test yesterday and saw some equations like this that the teacher hadn’t taught us yet, this just saved my grade!

Because of your vastness of lectures you should develop an application with proper play and sub playlists.

I'm here again. Thanks for sharing it with us

What would be the lcm if it was 1/3x +3y=6?

[wavyy_juan]

Im on 7th grade. My teacher said there is no such thing as adding or subtracting two different variables. So she was wrong😅☺

[hangezoeseyepatch]

So this can be use in any linear system of equations like graphing?

Minor mistake at 5:19: It's (8, 2), not (2, 8), unless I am wrong.

. When a number is multiplied by 2/3 the result is 5 less than the number. What is the number?

If a number is multiplied by 1.5 and then decreased by 70, the result is 25 less than the original number. What is the number?

I just want to know why did they add letters in math
