Snezhnost [94]

Step-by-step explanation:

it's late but I hope it helps :)

imagine that the > symbol is just an equal sign

so for example

x+2>4

will look like

x+2=4

and you solve normally

×=2

now we bring the symbol back

x>2

but if you multiple or divide by a negative the sign flips

so say you have

-2x>4

make it into

-2x=4

solve

x=-2

but instead of >

you put

x < -2

2(x -9) = 9 divided ( - 1/3) what value of x makes the equation true <br> plsss help :)))

Ivanshal [37]

Answer:

x = -9/2

Step-by-step explanation:

1. Divide 9 by -1/3:

$\frac{9}{1}$ ÷ $-\frac{1}{3}$ = $\frac{9}{1}$ · $-\frac{3}{1}$

= -27

2. Divide both sides by 2:

2(x - 9) = -27

$\frac{2(x-9)}{2} = \frac{-27}{2}$

(x - 9) = $-\frac{27}{2}$

3. Add 9 to both sides:

x = $-\frac{9}{2}$

(or 4.5 if you need it in decimal form)

hope this helps!
