Question

×+4y-z=6
2xt5y-7z=9
3×-2y+z=2

Answer 1

Respuesta:

×+4y-z=6

4y-z=6

4y-z-(-z)=6-(-z)

4y=6+z

4y/4}=6/4+z/4

y=6+z/4

2xt5y-7z=9

2xt.5y-7z=9

10yxt-7z=9

10yxt-7z+7z=9+7z

10yxt=9+7z

10yxt/10xt=9/10xt+7z/10xt;xneq0

y=9+7z/10xt;xneq0

3×-2y+z=2

3-2y+z=2

-3.2y+z=2

-6y+z=2

-6y+z-z=2-z

-6y=2-z

-6y/-6=2/-6-z/-6

y=-2-z6
