Question

find the sum 5m-7n,3n-4m+2,2m-5n+6
​

Answer 1

Let's simplify step-by-step.

5m−7n(3)n−4m+22m−5n+6

=5m+−21n2+−4m+22m+−5n+6

Combine Like Terms:

=5m+−21n2+−4m+22m+−5n+6

=(−21n2)+(5m+−4m+22m)+(−5n)+(6)

=−21n2+23m+−5n+6

Answer:

=−21n2+23m−5n+6

Answer 2

Answer:

$5m - 7n + 3n - 4m + 2m - 5n + 6+2 \\ \\ = 5m - 4m + 2m - 7n + 3n - 5n + 6+2 \\ \\ = 3m - 9n + 8$
