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>
