Best Answer

You have

- y = 4x + 8
- xÂ² + 7x - 2 = 0

xÂ² + 7x - 2 = 0

â†’ x = (-7 Â± âˆš(7Â² - 4Ã—1Ã—-2))/(2Ã—1) = (-7 Â± âˆš57)/2

â†’ x = (-7 - âˆš57)/2

â†’ y = 4 Ã— (-7 - âˆš57)/2 + 8 = -6 - 2âˆš57

or x = (-7 + âˆš57)/2

â†’ y = 4 Ã— (-7 + âˆš57)/2 + 8 = -6 + 2âˆš57

The solution is the two ordered pairs (x, y)::

( (-7 - âˆš57)/2, -6 - 2âˆš57) and ((-7 + âˆš57)/2, -6 + 2âˆš57)

Q: What is the solution to the system of equations y equals 4x plus 8 and x squared plus 7x - 2 equals 0?

x = 1 and y = 2

That system of equations has no solution. When the two equations are graphed, they turn out to be the same straight line, so there's no such thing as a single point where the two lines intersect. There are an infinite number of points that satisfy both equations.

there is no linear equations that has no solution every problem has a solution

A system of equations may have any amount of solutions. If the equations are linear, the system will have either no solution, one solution, or an infinite number of solutions. If the equations are linear AND there are as many equations as variables, AND they are independent, the system will have exactly one solution.

A pair of simultaneous equations in two unknowns which are inconsistent - in the sense that there is no solution that simultaneously satisfies both equations. Graphically, the equations are those of two parallel lines (slope = 2). Since, by definition, they cannot meet there is no solution to the system.
