here... if you still dont know the sign here it is Ax+By=C first step: write the equation... ex. [b]5x[/b]-4y= 4 second step: transpose [b]5x[/b] to the other side, it will become... -4y= [b]-5x[/b]+4 as you can see the positive sign becomes negative....when you transpose a number, you have to change its sign... third step: divide it by [b]-4y[/b] [b]-4y/-4[/b] = [b]-5x/-4 + 4/-4 [/b] when dividing like sign the answer is positive and when unlike sign negative... then...the answer is: [b]5x/4 -1[/b] [b]hope this will help... goodluck sis...!!![/b]
