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)
-10
There are two solutions and they are: x = -1 and y = 3
The solution of the system of linear equations ( x = 0 ) and ( y = 0 ) is the single point (0, 0) in the Cartesian coordinate system. This point represents the intersection of the two equations, where both variables are equal to zero. Thus, the only solution is the origin.
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.
x = y = 3
{-1,-2}
If "equations-" is intended to be "equations", the answer is y = -2. If the first equation is meant to start with -3x, the answer is y = 0.2
-1
No solution
