Get them to have a common denominator so you can add them
(1/3)×2= 2/6 and (1/2)×3= 3/6
Add them together
(2/6)+ (3/6)= 5/6
So 5/6 of the class planted either marigolds or tulips and 1/6 of the class planted neither

I have a photo that shows how I got the answer and what the answer is (Key: Red represents my work, while highlighter shows what the answer is):
Answer:
Step-by-step explanation:
The equation Thomas wrote is:
...equation 1
Let us subtract 3x from both sides to get:
We now multiply through by 2 to get:
....equation 2
We can see that equation one and two are equivalent and hence have the same solution.
Therefore Sandra's equation is
> y(1) = -5x + 3
-3. -3
> -2 = -5x
÷-5. ÷-5
= 0.4 = x
