Step-by-step explanation:
Represent white paint with w and black with b
Given
When w=3;b=1
Required
Determine the two equations
To get a gray paint, the w and b are needed in the following proportion:
3 * 1 = 1 * h
-=---(1)
Solve for b
3 * w =b
Reorder h= 3 * W
b=3w
-…~- This is an equation
To get another equation,
3 * W = 1 * b
Solve for w
3 * 10 = 6
3w = b
Make w the subject
w = =1/3b
Hence, the equations that show the relationship between w and b are:
w = =1/3b
and b= 3w
