Answer:
x - 2y = 32
Step-by-step explanation:
Start with y + 7 = (1/2)(x - 18).
Clear out the fractions by mult. both sides by 2:
2y + 14 = x - 18
Subtract 2y + 14 from both sides, obtaining:
0 = x - 2y - 14 - 18, or
0 = x - 2y - 32
Then x - 2y = 32. This is in standard form.

<u>Let's use PRT/100 to see what will be the total amount.</u>
- Total amount = Interest + Principle
<u>Solution:</u>
- PRT/100 = Interest
- => 2000 x 3.75 x 20 years/100
- => 20 x 3.75 x 20 = Interest
- => 2 x 2 x 375 = Interest
- => 4 x 375 = Interest
- => 1500 = Interest
- => Total amount = 1500 + 2000
- => Total amount = $3500
Hence, after 20 years, the amount earned is $3500.
