x2-8x=0
( add 8x to both sides)
x2 =8x
(divide by x)
x=8
( x2divided by x equals x)

In that case, x must be equal to zero. (0)
Yes it does equal 0. This is proved by commutative property of maths which says that 2 numbers can be multiplied in many ways.
x = -x; whence,x + x = 0; 2x = 0; and x = 0. This yields the un-surprising result that the only number that is equal to its negative is zero.
x - 6x = 0-5x= 0x = 0/-5which equals x = 0
Obviously, X is the variable which you are trying to get alone, and 0 is what the problem should equal. Basically, you're trying to get X by itself.
