Haley is at the store buying some supplies for an art project. She decides to buy some colored pencils for $3.95 and a drawing tablet. The total cost of the supplies before sales tax is $6.94.


Which equation could not be used to find the cost of the drawing tablet?


$3.95 + x = $6.94

$6.94 + x = $3.95

x = $6.94 - $3.95

$6.94 - x = $3.95
