Answer from: art3misdiangelo

C x = x = one-third

Step-by-step explanation:

What is the solution to the equation 3(x – 1) – 2(2x + 1) = 8(x – 1)?

x = x = negative StartFraction 4 Over 7 EndFraction

x = x = StartFraction 3 Over 7 EndFraction

x = x = one-third

x = x = two-thirds

C.?

Step-by-step explanation:

Hope this helps?

ansver

no, the answer is x = 12

Step-by-step explanation:

3(x + 4)= 2x - (-2x)

3(x + 4)= 2x + 2x

3x + 12 - 12 = 4x - 12

3x - 4x = 4x - 12 - 4x

-x = -12

x = 12

Answer from: mirandaperez3412

Step-by-step explanation:

3x - 3 - 4x - 2 = 8x - 8

Solving like terms

-x - 5 = 8x - 8

Bringing like terms on one side

-5 + 8 = 8x + x

3 = 9x

3/9 = x

1/3 = x

Answer from: arizola757

Step-by-step explanation:

3x+12=2x+2x

3x+12=4x

3x-4x=-12

-x=-12

x=12

Answer from: GiaTeyy6536

Step-by-step explanation:

3 {(x + 9)}^{ \frac{3}{4} }  = 24

3 {(x + 9)}^{\frac{3}{4} }  - 24 = 0

(3 \times  \frac{ {(x + 9)}^{3} }{4} ) - 24 = 0 \\  { \frac{3(x + 9)}{4} }^{3}  - 24 = 0 \\

\frac{ {3(x + 9)}^{3}  - 96}{4}  = 0 \\  \frac{3 {x}^{3} + 81 {x}^{2}  + 729x + 2091 }{4}  = 0 \\  3{x}^{3}  + 81 {x}^{2}  + 729x + 2091 =  \\  \frac{ 3( {x}^{3}  + 27 {x}^{2}  + 243x + 697)}{4} = 0 \\  \\  {x}^{3}  + 2 {x}^{2}  + 243x + 697 = 0 \\  \\ x =  - 5.825

x=(-5.825, -10.587, -10.587)

Answer from: mahkitheking16

x = 1/3

One-third

Step-by-step explanation:

3(x-1) -2(2x+1) = 8(x-1)

3x-3-4x-2=8x-8

-x-5=8x-8

Collect like terms

-x-8x=5-8

-9x=-3

Divide both sides by -9

x = 3/9

= 1/3

Answer from: eddy3625

x = 1/3

Step-by-step explanation:

3(x - 1) - 2(2x + 1) = 8(x - 1)

3x - 3 - 4x - 2 = 8x - 8

-x - 5 = 8x - 8

-9x = -3

x = 1/3

ansver
Answer from: nommies005

x = \frac{1}{3}

Step-by-step explanation:

Distribute parenthesis on both sides of the equation.

3x - 3 - 4x - 2 = 8x - 8 ← simplify left side

- x - 5 = 8x - 8 ( subtract 8x from both sides )

- 9x - 5 = - 8 ( add 5 to both sides )

- 9x = - 3 ( divide both sides by - 9 )

x = \frac{-3}{-9} = \frac{3}{9} = \frac{1}{3}
