repeating
Answer:
(x,y)=(3/2, -1/2)
Step-by-step explanation:
2x+4y=1 /*3
3x-5y=7 /*(-2)
6x+12y=3
-6x+10y=-14
...........................
/ 22y=-11
y= -11/22
y= -1/2
2x+4*(-1/2)=1
2x-2=1
+2 +2
2x=3
x=3/2
so the solutionis (x,y)=(3/2, -1/2)
Answer:3 lines could be used
Step-by-step explanation:
You need 2 points to draw a line. The order doesn't really matter. Line AB is the same as line BA. The problem is to select 2 points out of 3 to draw different lines. If we do the same to the others, we get the following pairs of points to draw lines.
AB , AC
BA , BC
CA , CB
which is only 3 lines
