Y=x+2 is the correct answer:)
10 you just substitute 5 in for x
<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
