3+6+7+89+4+5+7+9+90+67 = 287
-6y + 5 = -67y=12-6y = -72-y = -12y = 12
The answer is 82. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
5 + 6 + 2 + 1 = 14
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
6 + 5 + 3 + 2 + 9 = 25
2 + 3 + 4 + 5 + 6 = 20
