Hi,

sally has 12 coins consisting of highlight%28x%29quarters and highlight%2812-x%29dimes.

Question states*** the value adds to $2.25

Translate into an equation: CENTS makes sense

  25x + 10(12-x) = 225¢

       15x = 105¢

          x = 7, number of quarters.  5 Dimes

and...

25%2A7+%2B+10%2A5+=+225
