Question

I need help understanding what to do

Answer 1

a=-12 b=4 c=-1 d=-1/2

Explanation:

3*(-4)=a

-12=a

b*(-3)=-12

-3 -3

b=4

(-12)*c=12

-12 -12

c=-1

d*24=-12

24 24

d=-1/2

Answer 2

given below

if we change sides, multiplication becomes division and division becomes multiplication.

a = 4 * -3 = -12

b = -12/-3 = 4

c = 12/-12 = -1

d = -12/24 = -1/2
