Question

i need 459 not 720

Answer 1

I'm not sure how you got 720, unless you're guessing & checking. If 3(3x)=459 => 9x=459 is your work, it looks like you're on the right track. Now you just need to solve the equation 9x=459. Basically you need to ask yourself the question: What number do I multiply by 9 to get 459? Or, use the inverse operation (dividing) to find x.
