That’s what my tutor told me
Sum means add
(x+5) + (-4x-2) + (2x-1)
=-3x+3+(2x-1)
=-x+2
First subtract 4 from both sides

then simplify

add -5 to both sides

since a variable shouldn't be negative the answer should be

(I prefer having the variable on the left side)
Answer:
5y + 7
Step-by-step explanation:
Given:
Seeds planted in one garden = y vegetable seeds
Seeds planted in another garden = 4y + 7 vegetable seeds
To Find:
The number of seeds Val is going to plant = ?
Solution:
Let the total number of seeds that Val is going to plant be x.
Then
x = number of seeds planted in garden one + number of seeds planted in the other garden
Now substitute the values, we get
x = y + (4y+7)
x = 5y + 7
Answer:
The answer is D. Hope this helps!
