To solve for d, we can cross multiply:
d * 4 = 2 * 20
4d = 40
Divide both sides by 4:
d = 10

To solve for a, we can cross multiply:
4 * a = 10 * 6
4a = 60
Divide both sides by 4:
a = 15
4 * a = 10 * 6
4a = 60
Divide both sides by 4:
a = 15

To solve for a, we can cross multiply:
7 * a = 3 * 14
7a = 42
Divide both sides by 7:
a = 6
7 * a = 3 * 14
7a = 42
Divide both sides by 7:
a = 6
