Question

Find the solution to the system of equations. X+y+z=19 y+z=11 z=6

A.)x=19, y=11, z=6
B.)x=19, y=5, z=6
C.)x=8, y=7, z=4
D.)x=8, y=5, z=6

Answer 1

D. bc z=6 and y=5 so You have 11 and subract 19 from 11 and you 8 and thats what x equal.

Answer 2

the answer is D because if you subtract y+z=11 from 19 (19-11=8) you get 8 which is equal to X. If y+z=11 then y=5 because you subtract 11-6.

SO YOUR ANSWER IS D!!!
