multipling the negative through the parenthesis gives you
8d --7c--2d
double negative is a positive so you really have
8d + 7c + 2d
simplify (add the like expressions)
10d + 7c

The answer is 6d+7c because the 2 negatives become a positve and then you subtract 2d from 8d and you get 6d + 7c

8d - (-7c - 2nd) = 8d + 7c + 2nd = 7c + 10d to learn, Subsitute d = 2, c = 3 into 8d - (-7c - 2nd) 8 x 2 - (-7 x 3 - 2 x 2) = sixteen - (-21 - 4) = sixteen - (-25) = sixteen + 25 = 40-one to learn, Subsitute d = 2, c = 3 into 7c + 10d 7 x 3 + 10 x 2 = 21 + 20 = 40-one hence the equation is right. desire this helps.
