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
