I found that x = 8 and y = -2 because when you first subtract 2x + 4y = 8 from 3x + 4y= 16, you end up with x = 8. Then pluging 8 back into the equation you solve and find y = -2.

Step-by-step explanation:
$9,300
First, multiply your beginning amount by the percent of interest: 3,000x0.07 = 210
Then, multiply your interest times the number of years:
210x30 = 6,300
Add you interest to your initial amount:
3,000 + 6,300 = 9,300
If proportional y increases at the same rate as x. The fraction y/x should simplify to the same fraction for all x-y pairs.
162 think of a square like a pool both sides have to be the same
