2x - 7y = 8
3x - 4y = -1 multiply the first equation by -3, and the second one by 2

-6x + 21y = -24
6x - 8y = -2 add boyh equations

13y = -26 divide by 13 to both sides

y = -2 substitute -2 for y in the first equation

2x - 7(-2) = 8
2x + 14 = 8 subtract 14 to both sides
2x = -6 divide by 2 to both sides
x = -3

Thus the solution is (-3, -2).
