Question

What is an estimate of the solution of the equation 6n+3=2? Use a table.

ok so I know the answer is -1/6 but its asking to use a table? does anyone know what kind of table you use for this and how I'd use it? thank you soo much

Answer 1

I guess you could form columns for "n" and "left side"

n ... LS
0 3
1 9
2 15 --- getting too big, looking for 2 on RS
-1 -3 ---- too low, so n is between 0 and -1
1/2 6 ---- too high
-1/2 -3 --- too low
so between 0 and -1/2
-1/4 3/2 ----- too low
so between -1/2 and -1/4
- 3/8 3/4 too low

etc till you get close to Right Side of 2

BUT, as you probably did:
6n + 3 = 2
6n = -1
n = -1/6

Good example of how to make a simple question more difficult than it has to be.

bro what?
