Jack is twice as old as Lacy. In three

years, the sum of their ages will equal to 54.

Write the equation and show all steps to

solve.

Lacy is 16 years old, and Jack is 32 years old.

Step-by-step explanation:

Lacy's age now is L.

Jack's age now is twice Lacy's age, so Jack's age now is 2L.

In 3 years, Lacy's age will be L + 3, and Jack's age will be 2L + 3.

In 3 years, the sum of their ages will be L + 3 + 2L + 3, and it will equal 54.

L + 3 + 2L + 3 = 54

3L + 6 = 54

3L = 48

L = 16

Lacy is 16 years old.

Jack's age is 2L.

2L = 2 (16) = 32

Jack is 32 years old.

Jack is 32 years old and lacy is 16
