Using the quadratic equation formula: x = -5-/+ the square root of 7
{-1,7}
There is only one equation - possibly due to the limitations of the browser. There are not enough equations to derive a solution.
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
There are an infinite number of ordered pairs that satisfy the equation.
The coordinates of every one of the infinitely many points on the line defined by the equation is a solution.
There is no solution since the equation is inconsistent.
x = 0 and y = 4
The equation does not have a solution.
-5
Without an indication of the equals sign, this is not an equation.
Not sure what you mean; that equation certainly has a solution.
It is negative 5.
It is a linear equation in x. The equation has the solution x = 0.
x = 19
One equation with two unknowns usually does not have a solution.
That is not a correct equation. The numbers on the left equal -16, not 0. This is an equation with no solution.
