Answer:
The solution is shown in the graph.
x= 2.3
y= 4.3
This is a simple conversion. 1 gram equals .0022 lbs, meaning this is what you have to do: 58g*(.0022lbs/1g). The grams cancel out, and you're left with pounds.
Let the age of Jen 2 years later be x,
age of jack two years later = 2x
total age of jack and jen now = 2x + x - 2 - 2
= 3x - 4
3x - 4 = 66
3x = 70
x = 70/3
= 23.3 (to three significant figures)
age of jen now = x - 2
= 23.3 - 2
= 21.3
Jen is 21.3 years old now.
