The difference between the coefficients 7 and 3 is 4, so one solution is
y = 1, x = -1.
Then the remaining solutions will be of the form
x = -7n-1
y = 3n+1
for some integer n.
_____
Some of the solutions are (for n=0, -1, -2, 1, 2)
(x, y) = (-1, 1), (6, -2), (13, -5), (-8, 4), (-15, 7)
<span>B) 84 + z = 180, since 42*2=84, 180-84=96, z=96</span>
No 01010010001 is not rational
Answer would be -19 and your welcome :)
