Answer:

Step-by-step explanation:

"Inversely proportional to x" in this situation is represented by a = k/x.

Find k:

Let a = 15 and x = 25, then calculate k:

15 = k/25)

Multiplying both sides by 25 yields k = 15(25), or k = 3/5

What is 12+5x=2x-9 step by step
Alja [10]

Answer:

  x = -7

How to:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

5°x-(2°x-9)=0

Pull out like factors:

21 + 3x  =   3 • (x + 7)

Equations which are never true:  Solve 3   =  0

<em>Solving a Single Variable Equation:</em>

Solve  :    x+7 = 0

Subtract  7  from both sides of the equation : x = -7
