Explicación paso a paso:
5x + 7y = -1
-3x + 4y = -2
° 5x + 7y = -1
5x = -1 -7y
x = -1-7y / 5
°-3x + 4y = -2
-3(-1-7y / 5) + 4y = -2
3+21y / 5 + 4y =-2
3 + 21y + 20y / 5 = -2
3 + 41y = -10
41y = -13
y = -13/41
5x + 7(-13/41) = -1
5x - 91/41 = -1
205x - 91 / 41 = -1
205x - 91 = -41
205 x = 50
x= 50/205
x=10/41
