Question

1/2 x2 yz,3/2 x2yz,-5/4 x2yz​

Answer 1

Step-by-step explanation:

Subtracting first 2 equations, we get ;

⇒y+3z=−5

⇒y=−3z−5

Substituting y in 3rd equation ;

⇒2x−3z−5+3z=1

⇒x=3

Substituting x in 1st equation ;

⇒y=z−1

Equating both y, we get ;

⇒−3z−5=z−1

⇒z=−1

Substituting x and z in either equation, we get ;

⇒y=−2

∴x=3,y=−2,z=−1
