PARCC Grade 8 Math Practice Test Questions

1. Which of the following equations have infinitely many solutions?

1. A: A is the only one that has infinitely many solutions because when the 3 is distributed across the parentheses, the resulting equation is 6x-15=6x-15. Because each side of the equation is identical to the other side, any value of x will make a true statement, so there are infinitely many solutions.
