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

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
