You just gotta egual the equation to Zero then you factorize and then you isolate your zero so it could goes like that
4(7x4)=5(5x7) 28x16 =25x35 28x25x1635=0 3x51=0 3(x  17)=0 x=17 cause (x17)=0 banned 08/20/08  scammer  tenjuna

okay im doing basic 8th grade algebra heres an example of what some of questions are like 0.4(7x4)=5(5x7) stuff like that im just wondering if their are ne tips to help me remember and get this stuff good thanks in advance. Alright heres what you do: First since you see the decimal to the *tenths* place, you multiply the whole thing by 10 like: 10*.4(7x4)=10*5(5x7) 4(7x4)=50(5x7) Then just work through it like so 28x16=250x350 35016=250x28x 334=222x 334/222=x You can still distribute the .4, but if your new to this, keeping them round numbers makes it easier to look at. Whatever place the decimal is like "tenth" or 'hundredth" multiply it by 10 or 100 respectively. So if it was .05(3x2)=4(3x4).. you see its to the 100th place, so you multiply it by 100 and get 5(3x2)=400(3x4). Just so long as you multiply both sides by the same number, it will have no effect on the answer itself. This post has been edited by foxshox: Nov 8 2007, 01:06 PM

Uhh actually, if you multiply by zero, it will give you 0=0, which is true. It won't give you a definitive answer, but it won't be wrong.
