Question

Add :
2m +5n +3; 8 m-3n +13 and -5m-7n-6​

Answer 1

Step-by-step explanation:

2m + 5n + 3 + 8m - 3n + 13 + (-5m -7n -6)

= 2m + 5n + 3 + 8m - 3n + 13 - 5m - 7n - 6

= 2m + 8m - 5m + 5n - 3n - 7n + 3 + 13 - 6

= 5m + 10n + 10

Answer 2

Answer:

= 5m-5n+10

Step-by-step explanation:

2m +5n +3; 8 m-3n +13 and -5m-7n-6

= 2m+5n+3+(8m-3n+13)+(-5m-7n-6)

= 2m+5n+3+8m-3n+13-5m-7n-6

= 2m+8m-5m+5n-3n-7n+3+13-6

= 10m-5m+5n-10n+16-6

= 5m-5n+10
