Shawna, Dexter, and Tilana are solving the equation -2.5(5-n)+2=15. Shawna says, “I can begin by dividing each side of the equat

ion by –2.5 to get 5-n-2/2.5=-15/2.5." Dexter says, “I can begin by distributing -2.5 to get -12.5+2.5n+2=15." Tilana says, “I can begin by multiplying each side of the equation by -1/2,5 to get 5-n-0.8=-6." Which students are correct?

Hi!
Shawna is correct because since it's multiplied to the 5-n you have to do the opposite which is division.
Dexter is also correct because after distributing you can continue solving, there is nothing wrong with that.
Hope this helps!
