-x + y = -3;
3x + 2y = 9  :| \text{Solve}

-2x+2y=-6;
3x+2y=9 

-5x=-15 

___________________________________________________

-5x=-15 

x= \dfrac{-15}{-5} 

x= \dfrac{15}{5}  

x=3

-2*3+2y=-6 

-6+2y=-6 

2y-6=-6 

2y=0 

y=0

For the first equation, -2x+2y=-6 so you take the second equation minus this new equation that would get you 5x=15 :)

Dafna1 [17]
Answer:
1/625

Explanation:
In case of multiplication of numbers with same base, we add the powers.
This means that:
a^x * a^y = a^(x+y)

Applying this to the given, we will find that:
(5^-1) * (5^-3) = 5^(-1-3)
                      = 5^-4
                     = 1/625

Hope this helps :)
