As to solve the given equation for x.
00:02
Well, the first thing i notice is we have decimals.
00:05
So we're going to want to get rid of those.
00:06
And notice that in each decimal, it goes to the hundredth place.
00:10
Therefore, we're going to multiply each side of our equation by 100.
00:14
Because remember, multiplying by 100 moves the decimal point two places to the right.
00:18
So when i take 100 and multiply it by the first term, i don't distribute it to everything.
00:24
Because it's multiplication, i only need to distribute it to one term.
00:27
So i'm only going to distribute it to our decimal value.
00:30
Well, 100 times 0 .04, you move to decimal point two places, it's just 4.
00:36
So we'll have 4 times x minus 12...
