Answer:

Step-by-step explanation:

-2x +38 = 2(3 + 3x)

-2x + 38 = 2*3 + 2*3x

-2x + 38 = 6 + 6x

Add 2x to both sides

38 = 6 + 6x + 2x  

Combine like terms

38 = 6 + 8x

Subtract 8  from both sides

38 - 6 = 8x

8x = 32

Divide both sides by 8

x = 32/8

x = 4

Answer:

x = 4

Step-by-step explanation:

  • -2x + 38 = 2(3 + 3x)

Use distributive property to multiply 2 by 3 and 3x

  • -2x + 38 = 2 ×3 + 2 × 3x
  • -2x + 38 = 6 + 6x

subtract 6x from both side

  • -2x + 38 - 6x = 6 + 6x - 6x

combine -2x and -6x to get -8x

  • -8x + 38 = 6

subtract 38 from both side

  • -8x + 38 - 38 = 6 - 38

subtract 38 from 6 to get -32

  • -8x = -32

divide both side by -8

[tex] \small \sf \frac{-8x}{ -8} = \frac{-32}{-8} \\ \\ \small \sf x = \frac{- 32}{-8}[/tex]

divide -32 by -8 to get 4

  • x = 4
