Answer 1

Answer:

Just equate the coefficients,

Step-by-step explanation:

2x+y=10(given)

y=10-2x ......(i)

x-y=-1 (given)

put the value of y from(i)

x-(10-2x)=-1

x-10+2x+1=0

3x=-11

x=-11/3

So y=10-2x=10-2(-11/3)=10+22/3=52/3

x-z=2 (given)

-11/3-z=2

z=-11/3-2

z=-17/3

Pls check the calculations .I did them in rush.
