3x + 3y + 3z = 27
x + 3y + 3z = 17
x - 2y - 5z = 0


A. x = -2, y = 4, z = 2
B. x = 5, y = 5, z = -1
C. x = 2, y = 5, z = 4
D. x = 4, y = 3, z = -2

Answer 1

b

Answer 2

let me check make sure

Answer 3

ok

Answer 4

yes b

Answer 5

want to know how to do it quick

Answer 6

take first line multiply it by -1 add it to second line u get -2x=10 x=5 and continue doing same application to find y and z
