Alright, here we have this equation where we have 0 .01 times x plus 50 is going to be added to plus 0 .03 times x minus 20.
00:19
And that is going to be equal to 4 .06.
00:24
So we have our equation.
00:26
Now all we need to do is distribute, combine like terms, and solve for x.
00:31
So i'm going to take 0 .01 and multiply it across, and i'll get 0 .01x, 0 .01, come now computer, 0 .01x, and then 0 .01 times 50 is going to give us 0 .5, so plus 0 .5, and then plus 0 .03x.
00:53
And then if we take 0 .03 times 20, we're going to get minus 0 .6.
01:00
And that is going to be equal to 4 .06.
01:04
Now we can combine like terms.
01:06
We have 0 .01x plus 0 .03x.
01:10
That's going to be 0 .04x.
01:13
And then we have 0 .5 minus 0 .6...
