Let xy x plus 2y and let xy x - z. Solve the following system of equations for x y and z (xy)z 4 x plus (x(y2))(-z) -2 (xy)(-z) 2?
To solve the system of equations given by ( xy = x + 2y ) and ( xy = x - z ), we can start by equating the two expressions for ( xy ). Setting ( x + 2y = x - z ) gives us ( 2y + z = 0 ) or ( z = -2y ). Substituting ( z ) into the other equation leads to a system that can be solved for ( x ) and ( y ). However, without numerical values or additional equations, we cannot find unique solutions for ( x, y, ) and ( z ).
How can you write the product of a number and a sum as the sum of two products?
x*(y+z) = x*y + x*z This is the distributive property of multiplication over addition.
How do you write 32 is the sum of an number z and 9 as an equation?
To express "32 is the sum of a number z and 9" as an equation, you can write it as: ( z + 9 = 32 ). This equation states that when you add the number ( z ) to 9, the result equals 32. You can also rearrange it to solve for ( z ) by subtracting 9 from both sides, resulting in ( z = 32 - 9 ).
If xz plus zy equals xy and xz equals zy then the point z is?
mid point of xy
How to changes mix fraction to improper fraction?
The mixed fraction XY/Z is equal to (XZ + Y)/Z.
What is xy plus z?
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.
If Z is the midpoint of XY then .?
Z is halfway between X and Y.
If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
What is xy cubed z squared plus y squared z plus xyz completely factorised?
The only common factor to all terms is yz. → xy³z² + y²z + xyz = yz(xy²z + y + x)
How can you write the product of a number and a sum as the sum of two products?
x*(y+z) = x*y + x*z This is the distributive property of multiplication over addition.
What is xy plus z equals 9 for y?
xy + z = 9Subtract 'z' from each side:xy = 9 - zDivide each side by 'x':y = (9 - z) / x
How do you write 32 is the sum of an number z and 9 as an equation?
To express "32 is the sum of a number z and 9" as an equation, you can write it as: ( z + 9 = 32 ). This equation states that when you add the number ( z ) to 9, the result equals 32. You can also rearrange it to solve for ( z ) by subtracting 9 from both sides, resulting in ( z = 32 - 9 ).
