So if you're okay working with decimals, you can actually solve this problem as it stands.
00:08
Distribute your 12 -100s, combine like terms, get x on one side, constants on the other.
00:16
Let's go ahead and use a method if you don't like decimals to get rid of them.
00:21
So if i multiply through by a power of 10 that will move my decimal to places, that's going to give me all whole numbers to deal with.
00:33
And every power of 10 moves the decimal one place.
00:37
I want to move a 2, so i need 10 to the power of 2, which is 100.
00:43
So i'm going to multiply everything on both sides by 100.
00:51
And on this side by 100.
00:54
0 .05 times 100 is 5.
00:57
0 .12 times 100 is 12 and 940 times 100 is 94 ,000.
01:15
Now i need to distribute the 12.
01:19
So that gives me 5x plus 12x equals 60 ,000...
