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>
