Good morning Sonny
y-4x=7
2y+4x=2
We need to solve -4x+y=7 for y
Now let's start by adding 4x to both sides
-4x+y+4x=7+4x
y=4x+7
Now substitute 4x+7 for y in 4x+2y=2 so we can find the value for x
4x+2y=2
4x+2(4x+7)=2
12x+14=2
Add -14 to both sides
12x=14-14=2-14
12x=-12
Now divide 12 to both sides so we can find x
12x/12=-12/12
x=-1
Now we need to find the value for y by substitute -1 for x in y=4x+7
y=4x+7
y=(4)(-1)+7
y=3
Work done ;)
Answer : x=-1 and y=3
(-1,3)

112 pound of wildflower will cover 375 square feet
1 pound of wildflower will cover 375/112 = 3.348 square feet
The greatest common factor between the expressions is 6v.

How to find the greatest common factor?</h3>
We have the expressions:
We can see that the smallest power of "v" is 1, and it appears on the second expression, so the greatest common factor will be a number times v.
To get the number, we need to find the greatest common factor between the 3 coefficients.
12, 30, and 42.
Rewriting these 3 numbers we can see that:
12 = 2*2*3
30 = 2*3*5
42 = 2*3*7
In all the cases we can see that the factor 2*3 appears, so that is the greatest common factor between the coefficients.
So we can conclude that the greatest common factor between the expressions is:
2*3*v = 6v
And we can rewrite:
- 12v^2 = (6v)*(2v)
- 30v = (6v)*(5)
- 42v^4 = (6v)*(7v^3)
