Question

A+b+c=0
-a-3b=0
-2a-2c=1
find a b c ​

Answer 1

Answer:

a= - 3/2

b= 1/2

c= 1

Step-by-step explanation:

A+b+c=0 -----> 1

-a-3b=0

-a = 3b

a= - 3b - - - - - >2

-2a-2c=1

-2(a+c) = 1

a+c = - 1/2 - - - - - - >3

Sub eq 3 in eq 1

1 => - 1/2+b=0

b=1/2

Sub b=1/2 in eq 2

2 => a= - 3(1/2)= - 3/2

a= - 3/2

Sub a= - 3/2 in eq 3

3 => - 3/2+c= - 1/2

c= - 1/2+3/2

c= (3-1)/2 = 2/2 = 1

c=1
