This problem asks us to solve for our variable x.
00:03
There's a couple different ways you can do this, and then the textbook distributes first.
00:08
So that's the way that i'll follow along with.
00:11
I will distribute each of those names.
00:13
So you get x over 4 plus 4 over 4 is just 1, is equal to 2x over 5 plus 3 5ths.
00:22
So now you have multiple fractions, so you need to multiply everything by the lowest common denominator, or lowest common multiple between 4 and 5, and that's going to be 20 all the way up to 20.
00:32
So multiply each of those by 20.
00:34
It should have no fractions left.
00:35
So 20x divided by 4 is 5x plus 20 times 1 is 20.
00:40
So 5x plus 20.
00:41
20 times 2 over here, 20 times 2 is 40x divided by 5...
