its 5 because if y is 3 then u have to ask yourself wat times 3 + 7 is 22
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
It equals 24.

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.
true
It is an expression in the form of: xy+7

if you meant 2x²+y²-xy=21x=(±sqrt(-7 y^2+168)+y)/4y=(±sqrt(-7 x^2+84)+x)/2
Yes.

It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
If I am correct, 9 plus 7 equals 112.
