Answer: A = - 10. B = 54. C = - 1008. D = - 1000

Step-by-step explanation:

a * 3 = - 30 You must divide 3 on both sides in order to get the a alone.

a * 3/3 = - 30/3 And once you divide 3 from both sides you end up with

a = - 10 And a equals negative 10

-9 * b = 45 You have to add 9 to both sides to get b alone.

-9 + 9 * b = 45 + 9 And you end up with with

b = 54 b equals 54

-84 * 12 = c Since the c is already alone all you have to do is solve the problem

-84 time 12 eqauls - 1008, its a negative because it has a negative in the equation

-1008 = c

d * 88 = - 88,000 You have to divide 88 from both sides to get the d alone.

d * 88/88 = - 88,000/88. And you end up with

D = - 1000 d equals negative 1000

a = - 10

b = - 5

c = - 1008

d = -1000

Step-by-step explanation:

a = - 30/3

b = 45/-9

c = - 84x12

d = - 88000/88
