So i'm going to start this equation by looking to clear my fractions, and so i'm looking for a number that i can multiply by that could be divided by both 2 and 4.
00:10
And so that number is going to be 4.
00:12
Now what's important to know is that even though there's only fractions here and here, i need to make sure that i multiply every single part of my equation by 4.
00:19
So first i would do 4 times 1 fourth, which would be 1, and that has an x attached to it.
00:26
Then i would do 4 times 1, which is 4.
00:31
Then i would do 4 times 2, which is 8, and then 4 times 1⁄2, which would be 2, and that also has an x attached to it.
00:41
So now i have an equivalent equation, but i don't have any fractions anymore.
00:46
The next thing that i notice is that on the left side of my equal sign and the right side, i have variables.
00:51
So i need to get these variable terms together, so i can either move 1x over, or i can move this.
00:57
Is technically a negative 2x over.
01:00
When you move a variable term, you can either add or subtract.
01:02
So if i were going to move 1x, i would subtract it because 1x minus 1x would be 0.
01:08
Or if i were to move negative 2x, i would add it...
