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.

xy^(2) - y + 2x = -3 And y = 7 Substitute for 'y' Hence x7^(2) - 7 + 2x = -3 49x + 2x - 7 = -3 51x = 4 x = 4/51 = 0.078431372....
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.
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
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
It equals 24.

It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
