Answer:
a) 3x + ky = 8
ky = 8 - 3x
x – 2ky = 5
x - 2(8 - 3x) = 5
x - 16 + 6x = 5
7x = 21
x = 3 (shown)
b) x-2ky = 5
sub x = 3, y = 1/2
3-2k(1/2) = 5
-2k = 2
k = -1

Answer:
X = - 6
Step-by-step explanation:
P = 2(L + W)
P = 258
L = 2W - 9
258 = 2(2W - 9 + W)
258 = 2(3W - 9)
258 = 6W - 18
258 + 18 = 6W
276 = 6W
276/6 = W
46 = W <=== here is the width
L = 2W - 9
L = 2(46) - 9
L = 92 - 9
L = 83 <== here is the length
