Answer:
Step-by-step explanation:
Let Justin's age be x
Arlene today is 1/4 x
Ten years from now
Arlene: 1/2 (x + 10) = 1/4 x + 10 Remove the brackets
1/2 x + 5 = 1/4x + 10 Subtract 1/4x from both sides.
1/2 x - 1/4x + 5 = 10 Combine
1/4x + 5 = 10 Subtract 5 from both side
1/4 x = 10 - 5 Combine
1/4 x = 5 Multiply both sides by 4
x = 5 * 4
x = 20
Arlene is 5 years old (1/4 20) right now
Answer: Last year, Arlene was 4 years old
