Answer:
y = -16
x = 2
Step-by-step explanation:
-×2/ -x - 5y = 78 ➡ 2x + 10y = -156 (whole equation multiplied with -2)
then add up two equations
2x + 10y = -156
-2x + 2y = -38 (2x will be eliminated)
12y = -192
y = -16
now you can find x using the value of y
if
2x + 10y = -156 ➡ 2x -160 = -156 ➡ 2x = -156 + 160 ➡ 2x = 4
