Answer:

First solve for

z

using the third equation

z

=

75

5

=

15

Now that we know

z

, we can plug it into the second equation and solve for

x

15

x

+

2

(

15

)

=

−

195

15

x

=

−

225

x

=

−

15

Now we can find

y

using the values of

x

and

z

and plugging them into the first equation
