Kayla's score on yesterday's math test was 12 points greater than Julianne's score. Let K represent Kayla's score. Write an algebraic expression to represent Julianne's score.
If Kayla's score was 12 points more than Julianne's score, than all we have to do is subtract 12 points from Kayla's score to get Julianne's :) Hope this helps!
