2X+15= -3x how do you work this equation

x = -3

Step-by-step explanation:

2x + 15 = -3x     (try to move the x-terms to one side, add 3x to both sides)

2x + 15 + 3x = 0

5x + 15 = 0 (subtract 15 from both sides)

5x = 0 - 15

5x = -15    (divide both sides by 5)

x = -15 ÷ 5

x = -3

Hope this helps!

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.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
