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 equation 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?

A) only Shawna and Tilana

B) only Shawna and Dexter

C) only Dexter and Tilana

D) Shawna, Dexter, and Tilana

 

Please help me~Hannah
