y - 5x
X = 15 - 5y
That depends on the value of x and y. As an expression, "x + y" can't be simplified.
To factor out the expression: x2y-y3 First factor out one "y": y(x2-y2) The expression x2-y2 is a difference of squares, which factors as well: (y)(x-y)(x+y) This is the simplest factoring of the original expression.
-2
y - 5x
2(xy)
yz - x
0.5*xy
4(x+y)
This phrase might be represented by the mathematical expression Y + (-5x). Because there is no additional information, you cannot determine what either Y or x is.
X = 15 - 5y
The expression xy + z represents the sum of the product of x and y with the value of z. This is a simple algebraic expression where x and y are variables representing numbers, and z is a constant value. To find the result of xy + z, you would first multiply x and y, and then add the value of z to the product.
As a term of an expression: x-y
It is x*x + y*y*y*y
The sum of x and y decreased by their product is (x + y)- xy.
xy-3 where x and y are the two numbers.
