−9x−15y=−6
9x+11y=14
 
 
 
 add both sides of equations
. −4y=8 ∣:(=4)
. y=−2
substitute the value of y to the first equation
3x+5⋅(−2)=2
3x−10=2 ∣+10
3x=12 ∣:3
x=4
Answer: x=4; y=−2→(4; −2)

6 percent intrest per year for 5 years I think is the same as 30 percent for 5 years
so $15,000 x .3 is $4500
$15,000 + $4500 = $19,500
not 100 percent sure if this is correct but I think its right. Sorry if im wrong.
