10=43–|17p+12|
You won't use the absolute sign here. Since you cannot add variable to number AND there are no negatives.
10=43–|17p+12|
10=43–17p+12
Add 12 to 43.
10=43–17p+12
10=55-17p
Add 17p on both sides.
10=55-17p
17p+10=55
Subtract 10 from both sides.
17p+10=55
17p=45.
Therefore, the answer is p=2.64705882353.

1. Consider a triangle with sides a, b and c.
2. a, b and c can be sides of a triangle only if each of these conditions hold:
i) a+b>c
ii) b+c>a
and iii)a+c>b
3. So the only condition for 3 numbers to be the side lengths of a triangle is that the sum of any 2 of them must be larger than the third number
4. This is called the "triangle inequality".
