p-3+2p-9=0

p+2p-3-9=0

3p-12=0+12=0

3p/3 = 12/3 p=4

**Ms. Sue**, Wednesday, April 13, 2011 at 4:31pmYes, it's correct.

You can prove it by substituting 4 for p in the original problem.

**peyton**, Wednesday, April 13, 2011 at 4:42pmMs Sue, Can you explain how you substitute the 4 for the p. I'm not sure if I have to add 2with the 4 or do I multiply 2 with the 4.

4-3+2( 4) -9 +0

**Ms. Sue**, Wednesday, April 13, 2011 at 4:46pmMultiply 2 * 4. The expression 2p means 2 times p.

p-3+2p-9=0

4 - 3 + 8 - 9 = 0

12 - 12 = 0
