Question

What is the sum of the expressions for n=-2n=−2 and m=5m=5 ?

Answer 1

Answer:

- 43

Step-by-step explanation:

Expression: (3m+2n−6) and (−4−6m+7n)

n= -2 and m=5

Before inserting the values, let's add both expressions.

(3m+2n−6)  + (−4−6m+7n)

3m+2n−6   −4 − 6m + 7n

-3m + 9n - 10

Inserting the values;

-3(5) + 9(-2) - 10

-15 - 18 -10

- 43
