Solve the equations in Variant 26 and Variant 31.

Variant 26

• 5x - 22 = -8x - 4
  13x = 18
  x = 18/13
• (4x - 3) - 2x = 5
  2x - 3 = 5
  2x = 8
  x = 4
• x + 5 = 2x + 3(5x+6)
  x + 5 = 2x + 15x + 18
  x + 5 = 17x + 18
  -13 = 16x
  x = -13/16
• 5 - 4(4x-3) = 3(5x+2)
  5 - 16x + 12 = 15x + 6
  17 - 16x = 15x + 6
  11 = 31x
  x = 11/31
• x - 2(5x-3) - 4(2-3x) = 1
  x - 10x + 6 - 8 + 12x = 1
  3x - 2 = 1
  3x = 3
  x = 1
• (2x - 1) + 2 = 2(9x - 3) - 1
  2x + 1 = 18x - 6 - 1
  2x + 1 = 18x - 7
  8 = 16x
  x = 8/16 = 1/2

Variant 31

• 4x - 11 = -5x - 12
  9x = -1
  x = -1/9
