[ (12 - n)/7 ] = -1
12- n = -7
-n = -19
n = 19
Answer:
85+(5x-10)=11x+3 (sum of two non-adjacent interior angle is equal to exterior angle )
75+5x=11x+3
75-3=11x-5x
6x=72
x=72/6
x=12
Step-by-step explanation:

Answer:
8x - 20
Step-by-step explanation:
3(x - 6) + 4 + 5x - 6 
Distribute 3 to (x - 6)
3(x) - 3(6) + 4 + 5x - 6
3x - 18 + 4 + 5x - 6
Simplify:
3x + 5x - 18 + 4 - 6
8x -18 - 2
8x - 20
