Answer:
(x,y): (6 , -3) or (-30/7 , 33/7)
Step-by-step explanation:
6x + 8y = 12
x = y + 9 or y = x+ 9
if x = y+9
6*(y+9) + 8y = 12
14y = -42
y = -3 and x = 6
if y = x+9
6x + 8*(x+9) = 12
14x = -60
x = -30/7 and y = 33/7

(a) 94. (b) 85
(a). the perimeter = 2l +2w ; l - length and W - width
: . 2l + 2(56) = 300
2l = 300 - 112
l = 188/2 =94m
(b) area = Lxw
8245 = 97w
w = 8245/97
= 85m
