52 (total books) minus 24 (fiction books) equals 28 (non fiction books)
You could use the distance formula to prove its the same line.
square root of (x2-x1)^2+(y2-y1)^2
(5-3)^2+(6-9)^2
4+9
square root of 13
(-2- -4)^2+(3-6)^2
4+9
square root of 13
this proves it is the same line.
E = amount she put for Education
CD = amount she put for a Certificate of Deposit.
so, whatever those amounts are, we know that all she got is 70,000 bucks total, so
E + CD = 70000.
how much is three times the CD? well, 3*CD or 3CD.
how much is 10,000 more than that? well 3CD + 10000.
since we know that the amount on Education was 10000 more than three times the CD, then
E = 3CD + 10000.

how much was it invested in the CD? well, CD = 70000 - E.
