Question

Sistema de ecuaciones lineales?
ayudaaa
5X + 2Y = 1
-3X + 3Y = 5

Answer 1

5X + 2Y = 1 (3)
-3X + 3Y = 5 (-2)

15x+6y=3
6x-6y=-10
---------------
21x=-7
x= -7/21
x= -1/3

5x+2y=1
5 (-1/3) +2y= 1
-5/3 +2y= 1
-5+6y/3=1
-5+6y=1 (3)
6y= 3+5
y= 8/6
y= 4/3


Comprobación

5x+2y=1
5 (-1/3) +2 (4/3) = 1
-5/3+8/3 = 1
-5+8/3=1
3/3=1
1=1
