Roxanne is two years younger than her brother. Three times Roxanne's age is less than
four times her brother's age diminished by 12.​

Sagot :

Answer:

B > 6

Solution:

Let R be Roxanne's age and B be her brother's age

R = B - 2

3R < 4B - 12

3B - 6 < 4B - 12

Add 12 to both sides and subtract 3b to both sides

Therefore the answer is B > 6
