I NEED HELP ASAP I SUCK AT MATH 1. Solve the system of equations using the substitution method.

2x+8y=4

x=−3y+5

(14, -3)
(10, 4)
(15, -2)
(3, -14)

2. Solve the linear system of equations using the linear combination method.

4x−9y=20

x−6y=20

x = 3, y = 5
x = -4, y = -4
x = 4, y = 4
x = 5, y = -3

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
