3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)
Answer:
No it will only move the geometric figure
I'm assuming it's 57. Because 1/2 can equal .5 and 56.5+.5=57
Answer: 17
21-4=17
4+17=21
21+17=38 and so on..
