Answer:

x=-1

y=2

z=1

Step-by-step explanation:

After substitution we add common terms and make y and z the subject

y= 3-z

z= - 3+ 2y

We substitue the y

z = - 3+2(3-z)

z= 1

and now we subtitute the z to find y

y= 3-z

3-1 = 2

y=2

Now we substitue y and z to find x

x= - 2 - 3/2 + 5/2

x= - 1
