1/2 (9x + 6y - 15)

1/4 (16x + 20)

1/3 (16x + 20)​

. . .

Step-by-step explanation:

1/2 (9x + 6y - 15)= 9/2x+3y+ -15/2

1/4 (16x + 20)= 4x+5

1/3 (16x + 20)​= 16/3x+20/3

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.
