Respuesta :
4.7 + x = 3.1
Subtract 4.7 from both sides to isolate x
x = 3.1 - 4.7 = -1.6
Subtract 4.7 from both sides to isolate x
x = 3.1 - 4.7 = -1.6
X= -1.5
4.7 + X = 3.1
move the x and it becomes
4.7 = 3.1- X
then divide 4.7 by 3.1. then you get 1.5 but you cannot have a negative variable so you make the 1.5 negative !
