Answer:
p=-5/3,1
Explanation:
Subtract 11 from both sides. 
-|3p+1|=-3-1 
−∣3p+1∣=−3−1 
 
2 Simplify -3-1−3−1 to -4−4. 
-|3p+1|=-4 
−∣3p+1∣=−4 
 
3 Multiply both sides by -1−1. 
|3p+1|=4 
∣3p+1∣=4 
 
4 Break down the problem into these 2 equations. 
3p+1=4 
3p+1=4 
-(3p+1)=4 
−(3p+1)=4 
 
5 Solve the 1st equation: 3p+1=43p+1=4. 
p=1 
p=1 
 
6 Solve the 2nd equation: -(3p+1)=4−(3p+1)=4. 
p=-\frac{5}{3} 
p=−
