If 16 - 7d = -3 d + 2, collecting like terms with "d" on the left side yields -4d = -14, or d = 14/4 = 7/2.
5de+9e+7d+10e=5de+7d+19e
Expressed algebraically, d + 7d = 8d.
The coefficient of 3+7d is 7
7d + 2 7 is the only coefficient
7d
7d - 2 = 12, solve for d:7d = 12 + 2, so7d = 14.d = 14 / 7, sod = 2
I'd rather choose D5100
A/N PVS-14 was the norm when I was in, although units which had lower priority for receiving new equipment still often used to older A/N PVS-7.
-5

2 - 7d = -75 7d = 2 - (-75) 7d = 77 d = 77/7 d = 11
7d-8=7 / 7d=7+8 / 7d=15 / d=15:7 / d=2,14285.....
it spooky
