Explanation:

Step1: Combine like terms for Q5

Group variable and constant terms:
$(-8m - 4m) + (-3 - 7)$

Step2: Simplify Q5 terms

Calculate sums:
$-12m + (-10) = -12m - 10$

Step3: Combine like terms for Q6

Group variable and constant terms:
$(12 - 20) + (-5c - 10c)$

Step4: Simplify Q6 terms

Calculate sums:
$-8 + (-15c) = -15c - 8$
