6mn+7pq+6ಕ್ಕೆ -mn+pq-1add

Answer 1

$Let \: A = 6mn + 7pq + 6 \: and$

$B = - mn + pq - 1$

$Sum \: of \: the \: expressions$

$= A + B$

$= 6mn + 7pq + 6 + ( - mn + pq - 1)$

$= 6mn + 7pq + 6 - mn + pq - 1$

$= 6mn - mn + 7pq + pq + 6 - 1$

$= (6-1)mn + (7+1)pq + 5$

$= 5mn + 8pq + 5$

Therefore.,

$\red{ Sum \: of \: the \: expressions }$

$\green { = 5mn + 8pq + 5}$
