3 represents the number of <span>of students who earned a score of “needs improvement” on the Chapter 6 test.
16=3+13 represents the number total </span><span>of students who earned a score of “proficient” on the Chapter 7 test.

-2/3x + 5 = 20 - x
subtract 5 from each side
-2/3 x = 15 -x
add x to each side
-2/3 x +x = 15
get a common denominator of 3 for the x terms
-2/3x + 3/3 x =15
combine like terms
1/3 x = 15
multiply by 3 on each side
x = 45
Answer: x=45
