Insert the point, x=-30, y=3:
y=kx
3=k*-30
3=-30k
-1/10=k
Answer:
50(115-y) + 25y = 4125 [from eq2]
5750 - 50y + 25y = 4125 [distribute]
5750 - 25y = 4125
-25y = -1625
y = 65 [divide both sides by (-25)]
There are 65 small boxes.
Put that value into either equation (now, which is easier?) to solve for x:
x = 115 - y
x = 115 - 65
x = 50
There are 50 large boxes.

The correct answer is :
14
Simplifying
15a + 7b = 0
Solving
15a + 7b = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-7b' to each side of the equation.
15a + 7b + -7b = 0 + -7b
Combine like terms: 7b + -7b = 0
15a + 0 = 0 + -7b
15a = 0 + -7b
Remove the zero:
15a = -7b
Divide each side by '15'.
a = -0.4666666667b
Simplifying
a = -0.4666666667b
