In this problem, we're being asked to solve the given equation for x.
00:03
Well, i notice we have a lot of decimals here that sometimes can be a little confusing.
00:08
So we want to multiply our entire equation by something that will move our decimal point over two places to the right, because that will get rid of both of our or all of our decimals.
00:19
Well, to move a decimal two places to the right, that means we have to multiply each term by 100.
00:25
So we multiply the first term by 100.
00:27
Again, we move the decimal point two places to the right, so that's 4x.
00:31
When we multiply the second term by 100, again, we move the decimal point two places, and then we'll fill in the blank with the 0.
00:37
So that's minus 20...
