Answer:
(2x + 16)/3x = 2/1
2x + 16 = 6x
4x = 16
x = 4
Aaliyah's pens = 2x = 2 × 4 = 8
the number of Maria's pen = 3x = 3 × 4 = 12 -----Part A
New ratio = (8 + 16)/6
24/6 = 4/1 = 4 : 1 --------- Part B Step-by-step explanation:
Answer: 4x + 2y
Step-by-step explanation: 1/2(6x-8y) = 3x - 4y
1/2 * 6x= 3x
1/2 * 8y = 4y
-3(x - 2y) = -3x + 6y
-3 * -2 = 6y
4x - 3x + 6y + 3x - 4y
= 4x + 2y
