Answer:

x=-5/13

taking note of the assumption made.

Step-by-step explanation:

(5x-4)+(8x+9)=0

to solve for X, assuming you meant '0' and not '=simply'

we have

5x-4+8x+9=0

group like terms and solve.

5x+8x-4+9=0

13x+5=0

subtracting -5 from both sides of the equation

13x+5-5=0-5;

13x=-5

<u>x=-5/13</u>

$\mathbb{A~N~S~W~E~R~:}$

$= r$ · $2$

➡ $\Huge \sf \mathbb \color{}\underline{\colorbox{ANSWER~WITH~EXPLANATION ~!}{}}$

$\mathfrak{apply~the~fraction~rule: }$ $a$ $\frac{b}{c} =\frac{a~. ~b }{c}$

$\mathfrak{apply~rule: }$ $a$ · $1 = a$

$r$ · $1$ · $4 = r$ · $4$

$=\frac{r~.~4}{2}$

$\mathfrak{divide~the~numbers~: }$ $\frac{4}{2} = 2$

$= r$ · $2$

So, your answer will be is :
