Question

Please solve it fast matrices​

Answer 1

Answer:

if it's a whole number, x=3 and y =4

if it's a integer, x=+3,-3 and y=+4,-4

Step-by-step explanation:

By Matrice Multiplication,

the first equation comes as,

$x^{2} +y^{2} = 25$

For the second equation,

$-2x^{2} +y^{2} = -2$

By solving these two equation, you get the value of x as 3 or -3

y = 4 or -4

if it's a whole number, x=3 and y =4

if it's a integer, x=+3,-3 and y=+4,-4
