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 are the solutions to the equations 3x -5y equals 16 and xy equals 7?
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
What is 5 plus 7 plus 7 plus 5 equals?
It equals 24.
2 plus 3 equals 8 3 plus 7 equals 27 4 plus 5 equals 32 5 plus 8 equals 60 6 plus 7 equals 72 7 plus 8 equals what?

If y equals 2x plus 1 and x equals 4y-2 what is the value of xy?
We havey = 2x + 1 = 2(4y-2) + 1 = 8y - 3 iff 7y = 3 iff y = 3/7 iff x = 4y - 2 = 12/7 - 2 = -2/7(using "iff" for the double-arrow "is equivalent to" symbol which my PC won't copy).Thus xy = (-2/7)(3/7) = -6/7.
Xy plus7 equals yx plus 7?
true
What xy plus xy?
It is an expression in the form of: xy+7
What's is xy plus 7?
It is an expression in the form of: xy+7
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
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
Is xy equals 7 a inverse relation?
Yes.
What are the solutions to the equations 3x -5y equals 16 and xy equals 7?
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
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 is 5 plus 7 plus 7 plus 5 equals?
It equals 24.
If 2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 9 plus 7 equals 96 9 plus 7 equals what?
96
Why is -7 plus -5 equals -2?
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
Is xy 7 inverse equation?
It is difficult to be certain. Limitations of the browser used by Answers.com means that we cannot see most symbols. Please resubmit your question spelling out the symbols as "plus", "minus", "equals". If the question is about xy = 7, then it is an equation of an inverse relationship. This is NOT the same as an inverse equation.
