Question

Julia's English test score is 11 points more than Juana's, and Juan's English test score is 6 points less than Juana's. Julia and Juan's scores are added to 183 points. What's the test score of Juana? Use the equation to solve the problem. Set the variable as J.

Answer 1

what equation?
Is J Julia's score, or Juan's, or Juana's?

in any case, use the equation; you apparently neglected to include it here.

Answer 2

We could do this:

let Juana's score be j
then Julia's score is j+11
and Juan's score is j-6

solve:
j+11 + j-6 = 183

etc

I agree with Steve that this is a poorly designed question. All 3 names start with J, so to suggest J as the variable is rather silly.
