Find two numbers, if sum is 3 and their difference is 21

x+y =3

x-y =21

2x = 24

x = 24/2

x = 12

12+y = 3

y = 3-12

y = -9

numbers are -9 and 12

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

b. x + 1
