Masamune

y = –2x – 1
y = 3 – x – 1
y = -x + 2

-x + 2 = –2x – 1
-x + 2x = -1 - 2
x = -3

y = –2(-3) – 1
y = 6 - 1
y = 5

Solution set: (-3, 5)

m - {n - [p + (m + n - p)]}
= m - {n - (p - p + m + n)}
= m - {n - m - n}
= m - {-m}
= m + m
= 2m

The thirtieth term of the following sequence -6, -4, -2, 0, ... is 52.
The common difference = 0 - (-2) = 2;
30th term = -6 + (30 - 1)*2 = -6 + 58 = 52
