3 yrs ago:
Alice - x
Jane - 3x
Fast forward 2 years... 1 year ago:
Sum of their ages = 62
Equation to solve: x + 3x = 62
4x = 62
----- -----
4 4
x = 15.5
From this, we can deterime that Alice is 15 1/2 years old.
Then, plug in 15.5 for x in 3x to find Jane's age.
15.5 × 3 = 46.5
From this, we can determine that Jane is 46 1/2 years old.
I hope this helps you to understand this problem better.

C. -38
Step-by-step explanation:
We know that if the denominator is not given, then it is 1
So,
(-5/1) = (y-7/9)
Now, cross-multiply and set them equal
-45 = y - 7 Add both sides by 7
-38 = y
