Answer:

[tex]c = 5[/tex], explanation for how to get there

Step-by-step explanation:

If we have the equation [tex]4|3c+5| = 16c[/tex], we want to isolate c on one side and find it's value.

Let's first divide both sides by 4.

[tex]4|3c+5|\div4 = 16c\div4\\\\|3c + 5| = 4c[/tex]

Now let's solve for the absolute value. We know that:

[tex]3c + 5 = 4c[/tex]

or

[tex]3c + 5 = -4c[/tex]

Possibility 1:

[tex]3c + 5 = 4c[/tex]

Subtract 3c from both sides:

[tex]5 = c[/tex]

Possibility 2:

[tex]3c + 5 = -4c[/tex]

Add 4c to both sides:

[tex]7c + 5 = 0[/tex]

Subtract 5 from both sides:

[tex]7c = -5[/tex]

Divide both sides by 7:

[tex]c = \frac{-5}{7}[/tex]

Plugging both of these values into the equation, we can see that only 5 works.

Hope this helped!
