A sunflower in Julia's garden was 12 centimeters tall when it was first planted. Since then, it has grown approximately 0.6 centimeters each day. Write an equation expressing the sunflower's height, y, in terms of the number of days, d, since it was planted.
12 + 0.6d = y
y = 12 + 0.6d
What equation does this represent?

3x=9
