Whats 1+10? the answer is 11
114
Just use the Pythagorean theorem and then multiply by 2 to find answer. See picture to see how I did it.
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)
I dont really know maybe use the diagram it might help a lil
