Solve for X:
X divided by X + 30
so X / X + 30
Please show you work.

any number divided by itself equals one
so X/X + 30 =31
try it 1/1+30=31
104/104 +30 = 31

The answer. x=any real # except -30. X/(x+3)=0 so you can't multiply x+3 and 0 because then x=0, but that is only one anwser. But if you graph the equation you'll notice that any real # works except -30.

x/x + 30 = 31
this is because x/x = 1
therefore 1 + 30 = 31

X/X+30
If we take X/X+30=1/1,then
X/X+30 = 1/1
or X=X+30
or X-X=30
or 0=30

x/x+30=0 equate to zero, then find L.C.M which will give
1+30x/x=0 cross multiply
1+30x=x
30x-x=-1
29x=-1
so therefore; x=-1/29 [Ans]
