9-x/5=3. Solve for x

kari74 [83]

Answer:

$\boxed{\boxed{\sf x=-6}}$

Step-by-step explanation:

$\sf \cfrac{9-x}{5}=3$

$\sf \cfrac{5\left(9-x\right)}{5}=3\times \:5$

$\sf 9-x=15$

$\sf 9-x-9=15-9$

$\sf -x=6$

$\sf \cfrac{-x}{-1}=\cfrac{6}{-1}$

$\sf x=-6$

Marysya12 [62]

Answer:

$-2x^{2} -7x-6$

Step-by-step explanation:

(2x + 3) (-x - 2)

distribute first term, to the second term:

2x(-x) + 2x(-2) + 3(-x) + 3(-2)

multiply:

$(-2x^{2})$ + (-4x) + (-3x) + (-6)

$-2x^{2} -4x-3x-6$

combine the like terms:

$-2x^{2}$ - 4x - 3x - 6

-7x

$-2x^{2}$ - 7x - 6

final answer :

$-2x^{2}$ - 7x - 6

hope this helped !!

Steps to sloving -2(x+3)=-10

FromTheMoon [43]

Answer:

<h2>x = 2</h2>

Step-by-step explanation:

$-2(x+3)=-10$ <em>divide both sides by (-2)</em>

$\dfrac{-2(x+3)}{-2}=\dfrac{-10}{-2}$

$x+3=5$ <em>subtract 3 from both sides</em>

$x+3-3=5-3$

$x=2$
