1. $12r - 8 - 12$

your answer
simplify *

1. $n - 10 + 9n - 3$

your answer

Explanation:

Step1: Combine like terms for 1)

$(-6 + 7)k$

Step2: Calculate coefficient for 1)

$1k = k$

Step3: Combine constants for 2)

$12r + (-8 - 12)$

Step4: Compute constant sum for 2)

$12r - 20$

Step5: Group like terms for 3)

$(n + 9n) + (-10 - 3)$

Step6: Simplify each group for 3)

$10n - 13$

Answer:

1. $k$
2. $12r - 20$
3. $10n - 13$
