(1/x) - (1/y) = (1/z) Get the left-hand side over a common denominator:- (y-x)/xy = 1/z Take the reciprocal of both sides:- z = xy / (y-x)
x+xy=8 xy=-x+8 y=-1+8/x
It is then x/y when simplified
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
If you're solving for x, then x = 3/y.
(1/x) - (1/y) = (1/z) Get the left-hand side over a common denominator:- (y-x)/xy = 1/z Take the reciprocal of both sides:- z = xy / (y-x)
xy/-3
x+xy=8 xy=-x+8 y=-1+8/x
It is then x/y when simplified
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
(a + b)/(xy)
If you're solving for x, then x = 3/y.
y=(x+2)/(x+10) xy+10y=x+2 xy-x=2-10y x(y-1)=2-10y x=(2-10y)/(y-1)
To solve the given terms is almost impossible in the absence of any plus, minus and equality signs.
If you mean, "x-3y = 12", then xy = 3y2 + 12y.
