The answer would be a decimal so the answer is 7.4161984871.
I believe the answer is C, x-3.
C - no solution
you take the second solution and times the entire equation by -1
then simply
and you get 0x + 0y = 20
J ---- P --- K
JP = 2x
PK = 7x
JK = 27
2x + 7x = 27
9x = 27
x = 27/9
x = 3
The value of P is 3.
JP = 2x = 2(3) = 6
PK = 7x = 7(3) = 21
