{-2x-5y=13
<u>{2x-5y=17    </u>(+)
<em />  -2x+2x-5y-5y=13+17
-10y=30     /:(-10)
y=-3
2x-5y=17
2x-5*(-3)=17
2x+15=17
2x=2
x=1
<em>Solution: (1; -3)</em>        
 
        
             
        
        
        
Answer:  If the time is 3 1/2 years (most reasonable assumption)
Her initial deposit was $160
Step-by-step explanation:  The basic formula for simple interest is 
<em>i = prt  i </em>is interest, P is principal (deposit) r is the percentage (converted to a decimal) and t is time, the number of years.
For this question, you have to rearrange the equation to solve for p.
So divide both sides by rt and you have 
p =  i/rt
Substitute the values given
p = 36.40/(0.065)(3.5)
