<span>Let’s
assign variables for each workers
Let x = number of boxes sorted by worker 1
Let y = number of boxes sorted by worker 2
Let Z = number of boxes sorted by worker 1
=> X = 3Y
=> X = 2Z
The equation would be:
=> X + Y + Z = 66
=> X + X/3 + X/2 = 66
=> 6X + 2 X + 3 X = 396
=> 11 X = 396
=> 11X / 11 = 396 / 11
=> X = 36
X = 36
Y = 36 / 3 = 12
Z = 36 / 2 = 18
=> 36 + 12 + 18 = 66

Remark
There are two formulas for doing this. I'll use the one that does not involve the slope. I think it will be easier for you to understand.
Step One
Decide which point is (x1,y1)
Since point P is 2/5 the way up from point A, we will call (x1,y1) point A
Step Two
Write the givens.
Point(A) = (-2,-3)
Point(B) = (3,2)
Step Three
Write the formula
x1 + ratio*(x2 - x1), y1 + ratio(y2 - y1)
Sub and solve.
-2 + 2/5 *(3 - - 2) , -3 + 2/5*(2 - -3)
-2 + 2/5(5) , - 3 + 2
-2 + 2 , - 1
P = (0 , - 1) <<<<<< Answer

Answer:
Step-by-step explanation:
in x+3y=4
x = 3y +4 y = -1/3x + 4/3
in -x+y=4
x = y−4 y = x+4
