Dear Student

Thank you for using CHegg !!

-2c1 -4c2 -2c3 = -6 .............................(1)

2c1 + c2 + 0c3 = 4 ..............................(2)

-2c1 + 0c2 + 0c3 = 2 ...........................(3)

=> c1 = -1

Substituting c1 in equation (2)

2(-1) + c2 = 4

c2 = 6

Substituting c1 and c2 in equation (1)

-2(-1) -4(6) -2c3 = -6

2 -24 -2c3 = -6

c3 = -8
