I really understood your explanation, and tbh this lesson really complicates me but since I've viewed your video, I'm really confident enough to answer my math exam. Just subscribed and I hope to see more helpful videos. Thank youu!! 😭💚
There was no internet when I was in high school. We had to look everything up manually or find someone who knew the topic. Good luck with your studies :)
You want the variable or what you are solving for on one side by itself. This is so you can say x is equal to this. x = some number Let me give you an example. 2x + 3 = 5 You want to solve for x, which means we want to isolate x. This will end up as x = some number 2x + 3 = 5 To get x by itself, you will just do the opposite of what's being done to x. First we have 3 that is added to 2x, we can get rid of that by subtracting 3 away from each side. Subtract 3 away from both sides: 2x + 3 - 3 = 5 - 3 2x = 2 Now, we have 2 that is multiplying x, we can get rid of that by dividing both sides by 2. Divide both sides by 2: 2x/2 = 2/2 x = 1 Now x is isolated and we have a solution. x is equal to 1, so if we plug a 1 in for x in the original equation the left and right sides will be equal. 2(1) + 3 = 5 2 + 3 = 5 5 = 5

Glad to hear that!
online school is so hard but thank goodness we got RUclips

What does Isolate the variable mean?
You want the variable or what you are solving for on one side by itself. This is so you can say x is equal to this.
x = some number
Let me give you an example.
2x + 3 = 5
You want to solve for x, which means we want to isolate x. This will end up as x = some number
2x + 3 = 5
To get x by itself, you will just do the opposite of what's being done to x. First we have 3 that is added to 2x, we can get rid of that by subtracting 3 away from each side.
Subtract 3 away from both sides:
2x + 3 - 3 = 5 - 3
2x = 2
Now, we have 2 that is multiplying x, we can get rid of that by dividing both sides by 2.
Divide both sides by 2:
2x/2 = 2/2
x = 1
Now x is isolated and we have a solution. x is equal to 1, so if we plug a 1 in for x in the original equation the left and right sides will be equal.
2(1) + 3 = 5
2 + 3 = 5
5 = 5
@@Greenemath oh cool thanks btw you helped me many times now gl with your future vids!
I have a assignment can you help me with it lol it’s 12 questions 😭😭
Yes post the questions in the comments and I'll show you how to do a few of them.
Why cancel the 5 in 4:38?
You are trying to isolate the variable x. Since you have x/5, we multiply both sides by 5. Now you have x by itself.
@@Greenemath isnt 5x5 25? if were multiplying how do they cancel out?
@ZachSwanson-tn4cr We are multiplying 5 by 1/5, which is 1.
tysm it helps me a lot!
Glad it helped!
Thanks you so much👍
You are welcome
