There is only one equation - possibly due to the limitations of the browser.
There are not enough equations to derive a solution.
i think its 10
(4.25, 0.25) is a solution.
The equation has infinitely many solutions.
x = 2.1374586088176875 x = -1.6374586088176875
the answer is y minus 10 divided by 2.
{-1,7}
The equation does not have a real number solution. Using the quadratic formula will give it's conjugate pair complex solution.
The required equation is: -7x = 63
{-1,-2}
x = 4 and y = 7
An equation where x equals 3.
Choose any value for "x", replace that in the equation, and calculate the corresponding value for "y".
