zero solutions. If you plot these two lines, you will see that they are parallel and do not intersect.

Two solutions and they are:- x = 0 and y = 3

Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x

There are no real solutions because the discriminant of the quadratic equation is less than zero.

That equation has no solutions.There's no number that can go in place of 'x' that canmake the equation a true statement.

Your question does not make sense.

one

It has two equal solutions for x which are x = 2 and x = 2

There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.

Only one. x = (c - b) / a

x = -½

It has 2 real solutions because the discriminant is greater than zero.

2.

2x - y = 8 x + y = 1 These are your two equations. They will have two solutions since you have two variables. The solutions are x=3 and y=-2

There are none. For this equation, there is nonreal answer, as the graph of the quadratic does not pass below the x-axis

The discriminant is -439 and so there are no real solutions.

If: 11x+25 = 7x+15 then there is only one solution and it is x = -2.5

None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.

As many solutions as there are points in the domain.
