Answer 1

1,8-ab+7,7bc-d-10,1+a

1,8-ab+7,7bc-11,1d+a

Answer 2

To add these three expressions, we need to add the corresponding components together:

(1,8a-bc)+(7,7bc-d)-(10,1d-a) = (1+7-10, 8a-bc+7bc-d-1d+a)

Simplifying the expression, we get:

= (-2, 8a+6bc-1d+a-bc-d)

Now we can combine like terms to get the final answer:

= (-2, 9a+5bc-1d-d)

Therefore, the simplified expression is (-2, 9a+5bc-2d).
