Answer:
4 light years
Step-by-step explanation:
(2.4·10¹³ miles)/(6·10¹² miles/ly) = 0.4·10¹ ly = 4 light years

The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
3x = -6y + 6 becomes x = -2y + 2 and then you substitute in 5( -2y + 2) + 4y = -14
-10y + 10 + 4y = -14
-6y = -24
6y = 24
y = 4
And then you put y in x = -2(4) + 2 to find x
X = -8 + 2 = -6
x = -6
Then you try in both
5(-6) + 4(4) = - 14 -> -30 + 16 is -14 ✔️
3(-6) + 6(4) = 6 -> -18 + 24 is 6 ✔️
