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
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
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
-10
There are two solutions and they are: x = -1 and y = 3
Which of the following best describes the solution to the system of equations below?3x + 6y = 10 9x + 18y = 30
7
x=3
x = 1 and y = 2
