2x > 4x - 6 [two x is greater than (>) four x minus six]
You need to isolate/get "x" by itself in the inequality:
2x > 4x - 6 Subtract 4x on both sides
2x - 4x > 4x - 4x - 6
-2x > -6 Divide -2 on both sides to get "x" by itself
[two negative signs cancel each other out and become positive]
[when you divide/multiply a negative number to both sides of an inequality, you flip the sign (< >)]
x < 3
