2x-4/5=4<br> plsss answer quick
nikdorinn [45]

Answer:

<h2>x = 12</h2>

Step-by-step explanation:

\frac{2x - 4}{5}  =4

First of all multiply through by 5 to eliminate the fraction

That's

5 \times  \frac{2x - 4}{5}  = 4 \times 5 \\ 2x - 4 = 20

Next using the addition property add 4 to both sides of the equation

We have

2x - 4 + 4 = 20 + 4 \\ 2x = 24

<u>Divide both sides by 2</u>

\frac{2x}{2}  =  \frac{24}{2}

We have the final answer as

<h3>x = 12</h3>

Hope this helps you
