-25
k = 2 7 + (5 x 2) = 17 (8 x 2) + 1 = 17
(1, 9)
-2y=x+8 is the answer
x=5
Sum Numb!
if it is -X then X=5 if it was minus X the X=10
(x-9)(X+8)
x+xy=8 xy=-x+8 y=-1+8/x
2x-3 = x+5 2x-x = 8 x = 8
8+4x
3x = x+8 so 3x-x = 8 hence 2x = 8 and so x = 4
8x - 5 + 3x + 17 = 155% 11x + 12 = 1.55 11x = 1.55 - 12 = -10.45 x = - (10.45/11) = - 0.95
