Soolve this system of equations

x^2 + z^2 = 10
3x + y= 9
y + z= 9


and


5x-2 -4z= 3
3x+3y + 2z= -3
-2x + 5y+ 3z = 3

x^2 + z^2 = 10
3x + y= 9
y + z= 9

Subtract equation 3 from equation 2

3x - z = 0

3x = z

x^2 + z^2 = 10

x^2 + (3x)^2 = 10

10x^2 = 10

x^2 = 1

x = 1 Or -1

z = +3 Or -3

y = 6 Or 12 ANSWER
