Question 62375
Just decide which side you want your variables to be on and move them there within the rules of algebra, then move everything else to the other side within the rules of algebra.  Whatever you do to one side, you also do to the other.
ex: 3x-7 = 4x+5
3x-4x-7=4x-4x+5
-x-7=5
-x-7+7=5+7
-x=12
-x/-1=12/-1
{{{highlight(x=-12)}}}
Check if x=-12 does the equation equal?
3(-12)-7=4(-12)+5
-36-7=-48+5
-43=-43 Yes. We're right!!!
Happy Calculating!!!
