d=-18

a=51

x=-4

c=13/3

Step-by-step explanation:

1. subtract 6 from both sides

divide both sides by - 2

2. add 2 to both sides

times both sides by 3

3. times both sides by 4

divide both sides by 9

4. multiply the 10 out into the parenthesis add the 10c and 2c to get 12 c

add 40 to both sides

divide both sides by 3
