00:00:00.000 --> 00:00:04.319
Here is the problem: negative 3x plus 2 equals 1.

2
00:00:04.769 --> 00:00:09.518
A linear equation in x: isolate x using inverse operations.

3
00:00:10.317 --> 00:00:11.768
Start with the equation.

4
00:00:12.218 --> 00:00:14.528
Subtract 2 from both sides.

5
00:00:14.978 --> 00:00:17.555
Divide both sides by negative 3.

6
00:00:18.355 --> 00:00:25.031
So the answer is x equals 1 over 3 approximately 0.33333333.

7
00:00:25.481 --> 00:00:34.653
Doing the same operation to both sides keeps the equation balanced. Undoing addition, then multiplication, leaves x alone.

8
00:00:35.453 --> 00:00:44.753
x equals 0.33333333: left side equals 1, right side equals 1, which checks out.
