Answer:
x=-3, y=1. (-3, 1).
Step-by-step explanation:
-x+5y=8
3x+7y=-2
----------------
3(-x+5y)=3(8)
3x+7y=-2
--------------------
-3x+15y=24
3x+7y=-2
------------------
22y=22
y=22/22
y=1
-x+5(1)=8
-x+5=8
-x=8-5
-x=3
x=-3

Answer:
14
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
__
You have ...
(x^3)(x^a) = x^17
x^(3+a) = x^17
Equating exponents, we get ...
3 +a = 17
a = 14
The missing exponent is 14.
