a to question,
8x + 40 + 7y - 14 = -5
8x +7y = -31. _ (1)
now, 2x + 16 -4-y= 5
2x - y= -7 _ (2)
now multiply by 7 in eq (2) and subtract eAch other,
14x -7y = -49
8x +7y= -31
_________
22x= - 80
x = -80/ 22= -40/ 11
now, put value of x in eq 2
2× -40/ 11- y = -7
-80/ 11+7 = y
-80+ 77/ 11= y
y= -3/ 11
so these are answers hope it is good for u.....
