Let's solve the problem given to us today! The problem is the following:

$\mapsto\quad\bf{19-4c=17}$

We need to find the value of c.

So first, we subtract 19 from both sides:

$\mapsto\quad\bf{-4c=17-19}$

$\mapsto\quad\bf{-4c=-2}$

Remove the minus from both sides

$\mapsto\quad\bf{4c=2}$

Divide both sides by 4:

$\mapsto\quad\bf{c=\cfrac{2}{4}}$

$\mapsto\quad\bf{c=\cfrac{1}{2}}$

Therefore, c = 1/2.

Answer as a fraction = 1/2

Answer as a decimal = 0.5 (which is exact)

The decimal value hasn't been rounded.

Here is one way to do the steps

$19 - 4c = 17\\\\- 4c = 17-19\\\\- 4c = -2\\\\c = (-2)/(-4)\\\\c = (1)/(2)\\\\c = 0.5\\\\$

I subtracted 19 from both sides (in step 2). Then I divided both sides by -4 (in step 4). The fraction reduces to 1/2 which converts to 0.5

Let's check the answer.

$19 - 4c = 17\\\\19 - 4*0.5 = 17\\\\19 - 2 = 17\\\\17 = 17\\\\$

Both sides are the same after simplifying. The answer is confirmed.
