So here we have an equation, x minus two -fifths equals negative 8 .15th.
00:08
In order to solve this equation, we have to get x by itself by adding 2 -fiths to both sides so that we remove the 2 -fifths from the side with the x.
00:22
So we get x equals negative 815th plus 2 -fits.
00:39
Now in order to add these, we have to make sure that they have the same least common denominator, this case would be 15.
00:46
So we multiply two -fifths by an equivalent fraction to 1 to change the denominator to 15.
00:54
So we have negative 815 plus 2 -fifths times 3 over 3.
01:09
And we get x equals negative 815th plus 6 .15th.
01:25
Now let's add the two together.
01:27
They have different signs, so we subtract the absolute value.
01:30
So we have 8 minus 6, which is 2.
01:32
Then we take the sign of the number with the biggest absolute value, which in this case would be 8th.
01:38
And since the negative number, we get x equals negative 2 over 15...
