So one of the ways you can solve this equation is just to put the 12 ,000 over 1, make it a proportion because a 1 doesn't affect that 12 ,000, and then you can cross multiply to create an equation to solve.
00:14
So if we do that, we get 12 ,000x because 12 ,000 times x is 12 ,000x equals, and then 1 times that whole equation is still this thing here, so i'll just put 12 ,000 over 10 ,000x plus that 500 million.
00:41
It'll take me a minute to write all those zeros out.
00:51
So i just crisscrossed and now i have an equation to solve.
00:54
I want to get the x's on the same side of the equation.
00:58
So i will subtract 10 ,000x from both sides, subtract it on that side of the equal sign, subtract it on this side of the equal sign.

When i do that, the like terms go together here...
