00:00:00.910 --> 00:00:04.830
Solve 𝑥 minus 67 equals 81.
00:00:06.470 --> 00:00:09.060
This is a one-step linear equation.
00:00:10.640 --> 00:00:14.810
Some number minus 67 equals 81.
00:00:16.340 --> 00:00:22.340
And to find what our 𝑥 is, we’ll need to add 67 to both sides of our equation.
00:00:25.710 --> 00:00:29.300
Negative 67 plus 67 equals zero.
00:00:29.730 --> 00:00:33.280
81 plus 67 equals 148.
00:00:34.920 --> 00:00:38.050
𝑥 plus zero would just be equal to 𝑥.
00:00:38.460 --> 00:00:42.110
And that tells us that 𝑥 equals 148.
00:00:43.430 --> 00:00:50.750
To check and make sure we’ve solved this correctly, we can plug in 148 for our 𝑥 value in the original equation.
00:00:51.190 --> 00:01:01.210
148 minus 67 equals 81, so 𝑥 equals 148.
