00:00:00.000 --> 00:00:04.470
Here is the problem: negative 8x plus 11 equals 0.

2
00:00:04.920 --> 00:00:09.773
A linear equation in x: isolate x using inverse operations.

3
00:00:10.573 --> 00:00:12.059
Start with the equation.

4
00:00:12.509 --> 00:00:14.901
Subtract 11 from both sides.

5
00:00:15.351 --> 00:00:17.928
Divide both sides by negative 8.

6
00:00:18.728 --> 00:00:23.860
So the answer is x equals 11 over 8 approximately 1.375.

7
00:00:24.310 --> 00:00:33.714
Doing the same operation to both sides keeps the equation balanced. Undoing addition, then multiplication, leaves x alone.

8
00:00:34.514 --> 00:00:42.339
x equals 1.375: left side equals 0, right side equals 0, which checks out.
