Solve the system by elimination.
14) 5x + 6y = -8
-2x + 8y = 24
my question is: when im solving by elimination how do i know which number to multiply with on both equations! that’s what confuses me.

x=-4, y=2. (-4, 2).

Step-by-step explanation:

5x+6y=-8

-2x+8y=24

2(5x+6y)=2(-8)

5(-2x+8y)=5(24)

10x+12y=-16

-10x+40y=120

52y=104

y=104/52

y=2

5x+6(2)=-8

5x+12=-8

5x=-8-12

5x=-20

x=-20/5

x=-4

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
