SOLUTION: How do I solve the following equation for P? -3 = (4000/(130-P))* ((130+P)/(6000+10000))

Question 155361: How do I solve the following equation for P?
-3 = (4000/(130-P))* ((130+P)/(6000+10000))
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
-3 = (4,000/(130-P))* ((130+P)/(6,000+10,000))
-3=4,000/(130-P)*(130+P)/16,000
-3=4,000(130+P)/16,000(130-P)
-3*16,000(130-P)=4,000(130+P)
-48,000(130-P)=520,000+4,000P
-6,240,000+48,000P=520,000+4,000P
48,000P-4,000P=520,000+6,240,000
44,000P=6,760,000
P=6,760,000/44,000
P=153.636 ANSWER.
PROOF:
-3=(4,000)/(130-153.636)*(130+153.636)/16,000
-3=-169.23*.0177
-3=-3
