Respuesta :

a + 0.3 = -2

isolate the a, subtract 0.3 from both sides

a + 0.3 (-0.3) = -2 (-0.3)

a = -2 - 0.3

a = -2.3

A. a = -2.3 is your answer

hope this helps


In loving memory of Malkea
First move 0.3 on the other side. Then combine like terms. So a=-2-0.3. So A.a=-2.3 is the correct answer.
