3x+2x-6=24

-2x -2x
X-6=24
+6 +6
X=30
What was the mistake made here in this equation explain

The mistake made here is in the step where -2x is subtracted from both sides of the equation. This should result in x - 6 = 24 - 2x, not x - 6 = 24. The mistake was not distributing the negative sign to both terms on the right side of the equation. Additionally, when adding 6 to both sides to solve for x, the correct equation should be x - 6 + 6 = 24 + 6, resulting in x = 30, not x = 30.
