Answer:

Step-by-step explanation:
It is given that a box contains 2 dozen pairs of contact lenses ,of which 8 pairs are tinted.
1 dozen = 12 units
Total pairs of contact lenses 
Tinted pairs of contact lenses = 8
Pairs of contact lenses not tinted = 24 - 8 = 16
If a pair of contact lenses is drawn at random from the box, then we need to find the probability that it is not tinted.



Therefore, the required probability is 
Answer:
x = -27
Step-by-step explanation:
4x+27=3x
Subtract 3x from both sides of the equation.
==> 4x + 27 -3x = 3x - 3x
==> 4x - 3x + 27 = 0
==> 1x + 27 = 0
Subtract 27 from both sides,
==> x + 27 - 27 = 0 - 27
==> x = -27
