A star system is a group of two or more stars that are held together by gravity. Astronomers have determined that more than half of all stars are members of star systems. A star system with two stars is called a binary star. The two stars orbit each other, held together by gravity.
Answer:
x = -2, y = 1
Explanation:
Finding X:
3x + 4y = -2
2x - 4y = -8
5x = -10
5x/5 = -10/5
x = -2
Why: Using the elimination method, you can eliminate 4y and -4y since they are opposites. Then its an addition problem; 3x plus 2x is 5x. -2 plus -8 is -10. From there it's "junk and divide"
Finding Y:
2(-2) - 4y = -8
-4 -4y = -8
+4 +4
-4y = -4
-4y/-4 = -4/-4
y = 1
Why: Because you found that x = -2, you can then plug it in one of the equations. From there its simple "junk and divide". Hope this helps this took a long time to type lol.
