Let's go ahead and solve this equation.
00:03
Now when they say solve this equation, what they want to know is what is this value of the variable t? and the way we find that value is by separating this t from everything else in the equation so that only the t is left alone on one side of the equal sign.
00:20
So if we look at our equation here, we have 3t plus 2 equals 0.
00:26
Well, let's start by moving this plus 2 over to the other side.
00:30
And the way you do that is by doing the opposite of what that plus two says.
00:35
So the opposite of plus two is minus two.
00:39
And you have to do it to both sides.
00:41
You can manipulate equations as long as whatever you do to one side of the equation, you're also doing to the other side of the equation.
00:50
So over here on the left, our twos cancel out because a positive two minus two is zero...
