Answer 2

Let's solve each equation step by step:

a) a(a^2 - 9)x = a + 3

First, we can simplify the equation by factoring a^2 - 9 as (a - 3)(a + 3):

a(a - 3)(a + 3)x = a + 3

Next, we can divide both sides of the equation by (a - 3)(a + 3) to isolate x:

ax = 1

b) a*x = a + 2

To solve for x, we can divide both sides of the equation by a:

x = 1 + 2/a

c) a*x = a - 2

Similar to the previous equation, we divide both sides by a:

x = 1 - 2/a

d) a*|x| = a

This equation tells us that the absolute value of x is equal to 1. So, x can be either 1 or -1.

e) 4 + a*x = 3x - 1

We can rearrange the equation by bringing all the terms involving x to one side:

a*x - 3x = -5

Next, we can factor out x from the left side:

x(a - 3) = -5

Now, divide both sides by (a - 3) to solve for x:

x = -5 / (a - 3)

These are the solutions for each equation. However, please note that the values of a and x can have restrictions depending on the context or specific conditions given in the problem.
