Answer:
-7(n+3)-8(1+8n)
Simplifying
-7(n + 3) + -8(1 + 8n)
Reorder the terms:
-7(3 + n) + -8(1 + 8n)
(3 * -7 + n * -7) + -8(1 + 8n)
(-21 + -7n) + -8(1 + 8n)
-21 + -7n + (1 * -8 + 8n * -8)
-21 + -7n + (-8 + -64n)
Reorder the terms:
-21 + -8 + -7n + -64n
Combine like terms: -21 + -8 = -29
-29 + -7n + -64n
Combine like terms: -7n + -64n = -71n
-29 + -71n
