Issac has completed two more pieces of homework then Richard who submitted X pieces of homework for the semester if the total number of pieces of homework submitted by the two boys is 12 how many pieces of homework did Isaac submit

7 pieces of homework

Step-by-step explanation:

This is an algebra problem. We first need to set up our algebra equation and we are going to find X (The amount of homework Richard submitted)

The algebra equation would be

X+X+2=12

*Combine like terms*

2X+2=12

Subtract 2 to both sides

2X=10

X=5

That means that Richard did 5 pieces of homework. We are not done yet because we want to find the amount of homework Isaac did. Earlier in the problem, it said that Issac did 2 more pieces of homework than Richard. Take Richard's number, 5 and add to 2 to it to get 7 pieces of homework.
