All right, just like every other problem thus far in this section, we're starting with an equation.
00:10
So in this case, 2x plus 7 equals 10.
00:15
And even though it looks a little bit more complicated, we're still following the exact same steps.
00:20
So our first goal is to get a 1 in front of the x, so that coefficient of 1, and get it independent all by itself.
00:28
So we're looking for an equation of the form x equals k, x equals sum number.
00:34
So the first thing that we can do is subtract 7 from both sides.
00:40
In other words, what we're doing here is making zero pairs, and we always have to do the same thing on both sides of the equation.
00:47
What this leaves us with is 2x equals 3.
00:51
Pause for a second.
00:53
What's our next step to get this coefficient of x equal to 1? hopefully, you're thinking of dividing each side by 2.
01:05
What this leaves us with is x equals 3 over 2.
01:10
You can leave this as a fraction.
01:12
It's also equal to 1 .5 in decimal form...
