Hi there.
3(2x-4)=5x -1

Answer : This is False
Because when we calculate 3(2x-4) we will find it equal to 6x - 12, for that reason 6x-12 doesn't equal to 5x-1

6x-12=5x-1
x=11
Why?
because x=11 makes left hand side equal to right hand side.
To prove,
input x=11 in the main equation,
3[2(11)-4]=5(11)-1
3(22-4)=55-1
3(18)=54
54=54
LHS=RHS
Thus, your explanation for "why" has been explained.Thank you!
