Answer 3

wait I got sorry for tagging:)

Answer 4

add equations 1 and 2

will give

2x + 6y + 4z = 14

or re-writing it

2x + 4z + 6y = 14

equation 3 says 2x + 4z = 26

substituting

26 + 6y = 14

or

6y = -12

y = -2

substitute it into the 1st equation to find x

2x + 3(-2) = 0

2x = 6

x = 3

to find z use

2x + 4z = 26

2(3) + 4z = 26

4z = 20

z = 5

so the solutions are

x = 3, y = -2 ans z =5
