Answer:

j = 2d - 3

d = 11

Step-by-step explanation:

a. If Dante has d candies, write an expression to represent how many candies Jessica has.

j = 2d - 3

b. If Jessica has 19 candies, write and solve an equation to find out how many candies Dante has.

19 = 2d - 3

add 3 to both sides

22 = 2d

Divide both sides by 2

11 = d

d = 11
