A) \[8\text{ }and\text{ 1}2\]
B) \[-\,8\text{ }and\text{ 1}2~\]
C) \[12\text{ }and\text{ }8\]
D) \[-12\text{ }and\text{ }8~\]
Correct Answer: B
Solution :
(b) LHS; \[\left[ 12+\left( -5 \right) \right]+a=7+a\] RHS; \[b\left[ \left( -5 \right)+\left( -8 \right) \right]=b-13\] Now \[7+a=b-13\] is true Fora\[=-8\]and \[b=12\]You need to login to perform this action.
