Answer:
[tex]a - b = 6 \\ a = 6 + b \\ \\ put \: the \: value \: of \: a \: in \: second \: eq - \\ 2(6 + b) - b = 4 \\ 12 + 2b - b = 4 \\ b = - 8\\ \\ a - b = 6 \\ a = - 2[/tex]
Answer:
a= -2, b= -8
Step-by-step explanation:
a – b =6 ......(i)
2a – b =4 ......(ii)
Subtract equation (ii) from equation (i), we get
-a=2
a=-2
Substitute the value of a in equation (i), we get
-2-b=6
-b=6+2
-b=8
b=-8
Therefore, a = - 2 , b = -8
