Question

TEST Solve the given Simultaneous Linear Equations : u - v - w = 4 , w - u - v = 6 and v - w - u = 8. [ 4 Marks ]
I hope that any 1 of the Brainly members can easily solve this Question.
I not, then he / she will fail in this Exam

Answer 1

u-v-w=4 --------(1)

-u-v+w=6. ----(2)

-u+v-w=8. ----(3)

add (1)&(2)

u-v-w-u-v+w=4+6

-2v=10

v=-5

add (2)&(3)

v and w are cancel

-2u=14

u=-7

add (1)& (3)

u and v are cancel

-2w=12

w=-6
