3p - (-20) = 50 what is p?

To get the answer you cancel out the minus of the negative 20 and change it to adding 20. then you subtract the 20 on both sides to get 3p=50-20. that would give you 3p = 30. then you would divide by 3 on both side. 3p/3=30/3. the 3 on 3p would cancel out so you will get p=30/3. the answer is p=10.

3p - (-20) = 50

3p+20=50 subtract 20 from both sides

3p=30 divide both sides by 3

p=10
