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!
