Question

Solve this inequality: 3p – 16 < 20

Answer 1

p < 12
1. add 16 over
2. divide all by 3

Answer 2

Solve this like the less than was an equal sign to start
3p-16<20
3p-16=20
Add sixteen to each side
3p-16+16=20+16
3p=36
Divide each side by 3 to get p by itself:
3p=36
p=12
Replace the equal sign with the less than sign again
p<12
