A teacher asked her students to solve the equation w-9=28. One student incorrectly said that the solution is 19. What is the correct​ solution? What mistake might the student have​ made?
The solution is
nothing. ​(Type the value of w​.)

Respuesta :

Answer:

37

Step-by-step explanation:

In the order of solving an equation you do the opposite of the original sign(-). so you add 9 on both sides of the equal sign and your left with w=37.
The correct solution is 37. The student subtracted 9 from 28 instead of evening out the equation by adding 9 to 28, which resulted in the incorrect answer
