2(4+x)

Distribute the 2 onto the 4 and x

2*4 = 8
2*x = 2x
—————
2x+8
—————
To evaluate, do 2x+8=0 (isolate x)

Subtract 8 on both sides

2x=-8

Divide by 2

X=-4

I hope I helped you out :)

If one-sixth of a number plus one-third returns two-thirds of that number What is the number

Solnce55 [7]

Answer:

$x= \frac{2}{3}$

Step-by-step explanation:

Let the number be x

Given

$\frac{1}{6}x + \frac{1}{3} = \frac{2}{3}x$

Required

Find x

$\frac{1}{6}x + \frac{1}{3} = \frac{2}{3}x$

Collect Like Terms

$\frac{1}{6}x - \frac{2}{3}x = - \frac{1}{3}$

Take LCM

$\frac{1 - 4}{6}x = \frac{-1}{3}$

$\frac{- 3}{6}x = \frac{-1}{3}$

Multiply both sides by 6

$6 * \frac{- 3}{6}x = \frac{-1}{3} * 6$

$-3x= -2$

Divide both sides by -3

$\frac{-3x}{-3}= \frac{-2}{-3}$

$x= \frac{2}{3}$

Hence, the number is $\frac{2}{3}$

(4 - 3x) is greater than or equal to -9

dalvyx [7]

Answer:

x ≤ 13/3

Step-by-step explanation:

4 - 3x ≥ -9

Isolate the variable, x. Treat the ≥ sign as an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 4 from both side:

4 (-4) - 3x ≥ -9 (-4)

-3x ≥ - 9 - 4

-3x ≥ -13

Next, divide -3 from both sides. Note that when you divide by a negative sign, you must flip the sign:

(-3x)/-3 ≥ (-13)/-3

x ≤ (-13)/(-3)

x ≤ 13/3

x ≤ 13/3 is your answer.
