Equate -2b-c=-1 and b+c=0

Answer»

\huge \purple {Answer}

• -2b-c=-1

=> -(2b+c)=-1

=> 2b+c=1 -(i)

• b+c=0 -(II)

From (ii),

b=0-c

Substitute this VALUE of b in (i),

2(0-c)+c=1

0-2c+c=1

-c=1

\boxed {c=-1}

Use value of c in (ii),

b+(-1)=0

b-1=0

b=0+1

\boxed {b=1}

Therefore, value of b= 1 and c= -1

\boxed {Hope \: it \: helps}
