Answer:

x=7/5

Step-by-step explanation:

Answer:

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

Step-by-step explanation:

We have been given an equation [tex]5x+(3x-\frac{4}{5})=12[/tex]. We are asked to solve the given equation.

First of all, we will remove parentheses as:

[tex]5x+3x-\frac{4}{5}=12[/tex]

Now, we will combine like terms.

[tex]8x-\frac{4}{5}=12[/tex]

Upon adding [tex]\frac{4}{5}[/tex] on both sides of equation, we will get:

[tex]8x-\frac{4}{5}+\frac{4}{5}=12+\frac{4}{5}[/tex]

[tex]8x=12+\frac{4}{5}[/tex]

Now, we need to make a common denominator.

[tex]8x=\frac{60}{5}+\frac{4}{5}[/tex]

[tex]8x=\frac{60+4}{5}[/tex]

[tex]8x=\frac{64}{5}[/tex]

Our last step is to divide both sides by 8 as:

[tex]\frac{8x}{8}=\frac{64}{5\cdot 8}[/tex]

[tex]x=\frac{8}{5\cdot 1}[/tex]

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

Therefore, [tex]x=\frac{8}{5}[/tex] is the solution of our given equation.
