Your serial number indicates that you have a Browning light weight auto-5 shotgun that was made in Belgium by FN for Browning in the year 1963.
your browning auto-5 lightweight 20 ga was made in 1963.As to value they are going between 450-650 dollars depending on condition.
-47 + 6z = 3z-2-3z -3z-47 + 3z = -2+47 +473z = 45/3 /3z = 15
15 = 3z - 6 15 + 6 = 3z 3z = 21 z = 7
Collect all the letters on one side and the numbers on the other; what you do to one side of the equals you do to the other: 3z + 2 = 6z - 13 → 3z +2 - 3z = 6z - 13 - 3z → 2 = 3z - 13 → 2 + 13 = 3z - 13 + 13 → 15 = 3z → 3z = 15 (this is just changing the equals around so that the letter is on the left) → 3z ÷ 3 = 15 ÷ 5 → z = 5
Since 9z is a multiple of 3z, it is automatically the LCM.
-6z 2 = 3z+ 4z+28 -6z+2 +3z = 3z+ 4z +28 +4z -6z+4z+2 = 3z+ 28 -10z+2 -3z= 28 - 2 -10z + -3z = 26 -13z/13 = 26/-13 z = -2
-3z - 9 = 24 ⇒ -3z -33 = 0 (subtract 24 from both sides) ⇒ -33 = 3z (add 3z to both sides) ⇒ -11 = z (divide both sides by 3) ie z = -11
3z equals z - 24 = -21
It's rare to see an equation with two equals signs. I'm guessing something else went in between 3z and 9. 3z + 9 = 15, then z = 2 3z - 9 = 15, then z = 8 3z x 9 = 15, then z = 5/9 3z/9 = 15, then z = 45
The value will be mainly determined by engraving. Who did it? Is it factory or aftermarket? Was it special ordered? Any accessories come with it? What type of wood used in the stock? Value range could be 100-1000 USD or more.
9z+8 = 3z-10 9z-3z = -10-8 6z = -18 z = -3
