5x2 - 2y2 = -20

7x2 - y2 = 152

Eq1 - 2*Eq2: -9x2 = -324

so that x2 = 36

Substituting the value of x2 in Eq1: 2y2 = 200 so that y2 = 100

The four solutions are (-6, -10), (-6, 10), (6, -10) and (6,10)

Q: Solution to the following system of equations 5x2 - 2y2 equals -20 7x2 - y2 equals 152?

There are two solutions and they are: x = -1 and y = 3

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
