If 𝑥 minus two is equal to nine, what is the value of 𝑥?
00:00:06.890 --> 00:00:10.700
In order to solve this equation, we are going to use the balancing method.
00:00:11.840 --> 00:00:15.960
Our first step will be to add two to both sides of the equation.
00:00:16.320 --> 00:00:22.420
This will leave us 𝑥 minus two plus two equals nine plus two.
00:00:23.530 --> 00:00:29.390
As negative two plus two gives us zero, the left-hand side will just become 𝑥.
00:00:30.150 --> 00:00:33.890
On the right-hand side, nine plus two equals 11.
00:00:34.230 --> 00:00:37.430
Therefore, our value for 𝑥 is 𝑥 equals 11.
00:00:38.150 --> 00:00:42.930
We could check this answer by substituting the 11 back into the initial equation.
00:00:43.370 --> 00:00:45.990
11 minus two is equal to nine.
00:00:46.450 --> 00:00:49.920
Therefore, our solution 𝑥 equals 11 is correct.
