Xy plus 7 equals 22 where y equals 3?
its 5 because if y is 3 then u have to ask yourself wat times 3 + 7 is 22
What numbers multiplied equal 22 but added equal 22?
44
Find two whole numbers whose product is 147 and whose quotient is 3?
xy = 147 x/y = 3 x = 21 y = 7
What is the sum of seven and the product of x and y?
7+xy
What is the differentiation of xy=x^3+y^3?

If the sum of two numbers is 7 and there product is 25 what is the sum of there reciprocals?
Suppose the two numbers are x and y. Then, the sum of THEIR reciprocals is 1/x + 1/y = y/xy + x/xy = (y + x)/xy = 7/25
If x y = xyâxây, what is the value of 2 (3 4)?
*Hint*=xy=x mutiplied by y.

How do you rewrite this equation so that y is a function of x 2x plus y equals 7?
y=f(x)= x(2x+y)=7 f(x)=2x^2 +xy -7 = 0 y=2x^2 +xy -7 y-xy -7 + 2x^2 = 0 y(1-x)=2x^2-7 y=(2x^2-7) / (1-x) Excuse the working. Y equals 2 X squared minus 7 all divided by 1-X
What multiplies to -30 and adds to -7?
-37
The sum of two number is 10 and their product is 30 the sum of their reciprocals is?
Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
What is the sum of seven and the product of x and y?
7+xy
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 the differentiation of xy=x^3+y^3?
6
2x2 plus y2 - xy equals 21?
if you meant 2x²+y²-xy=21x=(±sqrt(-7 y^2+168)+y)/4y=(±sqrt(-7 x^2+84)+x)/2
