Question

Given: a = -7, b = 6, c = 12 and d=-15.
From the sum of b , c,d the difference of d and a is subtracted. What is the result?

Answer 1

Answer:

25

Step-by-step explanation:

6+12+(-15)-(-15)-(-7)

18-15-(-15)+7

3+15+7

=25

Answer 2

Step-by-step explanation:

b+c+d= 6+12 + (-15)=18-15=3

d-a= -15- (-7) = -15+7=. -8

(b+c+d) - (d-a) = 3 - ( -8)=3+8=11
