Reasoning with linear equations | Solving equations & inequalities | Algebra 1 | Khan Academy

When we perform operations to manipulate equations, some operations produce equivalent equations, while others don't necessarily produce equivalent equations. When we're solving an equation, we need to use operations that guarantee equivalence.

Another way to solve the 5x=6x situation is to split it into two cases:
1)
if we assume x≠0, then we can divide by x and see that 5=6 has no x satisfying it.
2)
if we assume x=0, then we can plug it in and see that 0=0 is satisfied.

This is obviously needlessly complicated as opposed to the method presented in the video, however, it's a nice excercise for your logical thinking, which is quite important later on in your math learning journey.

I gotta watch all these vids on this and i don’t have a clue what’s happening lmao I’m failing math with an F

my teacher gave us these videos during quarantine to watch to understand a subject and these are actually really helpful that's why I subbed 😎

I can solve all of these but don't know the word selections they want us to pick.

That is what I got:5x=6x. 5x_6x=0.

Hi Salman or whoever runs the chanell,
Could you please tell me what software you guys use for drawing equations out.
Thanks Zarif

Is there anyone who know in which apps it is possible to write like this

[newplayer]

I watched yet it doesn't make sense

[aeminadabhagos]

Do you know guys I guess the answer I swear to God x equal 3
