Despejamos y en la 1ra ecuacion
3x - 2y = -2
3x + 2 = 2y
y = (3x + 2)/2
Luego sustituimos y en la 2da ecuacion
5x + 8y = -60
5x + 8[(3x+2)/2] = -60
5x + 4(3x + 2) = -60
5x + 12x+ 8 = -60
17x = -60 - 8
x = -68/17
Entonces en
y = (3x + 2) / 2
y = [3(-68/17) + 2] / 2
y = [(204 + 34)/7] / 2
y = 238 / (7 *2)
y = 238 / 14
y = 17
