Answer:

[tex]\frac{21}{10}[/tex]

Step-by-step explanation:

x - [tex]\frac{8}{5}[/tex] = [tex]\frac{2}{4}[/tex]

x= [tex]\frac{2}{4}[/tex] + [tex]\frac{8}{5}[/tex]

Now pay attention.

First,  multiply the bottom 2 numbers (4 x 5), that goes on bottom of fraction : [tex]\frac{}{20}[/tex]

Then cross multiply : (4x8) and (2x5) and add them. Put it on top of fraction:

[tex]\frac{32 + 10}{20}[/tex]

[tex]\frac{42}{20}[/tex]

Then reduce fraction:

[tex]\frac{21}{10}[/tex]

I call it the butterfly effect.
