Answer:

x=−15

Explanation:

Rearrange terms:

  • 5x + 2(11 - 4x) = 82 + x
  • 5x + 2(- 4x + 11) = 82 + x
  • Distribute:
  • 5x + 2(- 4x + 11) = 82 + x
  • 5x - 8x + 22 = 82 + x
  • Combine like terms:
  • 5x - 8x + 22 = 82 + x
  • - 3x + 22 = 82 + x

Rearrange terms:

  • - 3x + 22 = 82 + x
  • - 3x + 22 = x + 82

Subtract 22 from both sides:

  • - 3x + 22 = x + 82
  • - 3x + 22 - 22 = x + 82 - 22

Simplify:

  • Subtract the numbers
  • Subtract the numbers
  • -3x = x + 60

Subtract x from both sides:

  • -3x=x+6 x = x + 60
  • -3x-x = x + 60-x
  • Simplify:
  • Combine like terms
  • Combine like terms
  • -4x = 60

Divide both sides by the same factor

  • -4x = 60
  • -4x/-4 60/-4

Simplify

  • Cancel terms that are in both the numerator and denominator
  • Divide the numbers
  • x = -15

Answer:

we develop

5x + 2(11-4x) = 82 + x

5x+22-8x=82+x

we reduce

-3x+22 =82+x

we solve

-3x-x=82-22

-4x=60

x=-15
