Caitlyn spends $17 at the store. She buys a mop for $5 and 3 bottles of floor cleaner. If x represents the cost of each bottle of cleaner, the equation that can be used to find the value of x is . Which shows the first step that should be taken to verify that $4 is the solution to the equation?

Respuesta :

 5+3x=17
-5        -5
-------------
3x=12

Divide both sides by 3. X=4

You can plug the puppy in and verify that 4 is the answer.

17-5 es igual a 12 luego se divide por 3 y da 4

17-5= 12/3= 4
