Question

Describe and correct the error in the solution. (Be specific and explain as

much as you can. What is the correct solution?) *
5(p+3) > 4p + 2
5p+3 > 4p + 2
5p > 4p - 1
p>-1

Answer 1

You can see where they messed up in the second step. 5(p+3) should be distributed correctly. It should be 5p+15.

The correct solution would be p>-13

Answer 2

In the second step, 5 should have been distributed to both the p and the 3. To correct this, step two should say 5p+15>4p+2
