Answer:

solution,


0.18(5x - 4) = 0.5x + 0.8 \\ or \: 0.9x - 0.72 = 0.5x + 0.8 \\ or \: 0 .9x - 0.5x = 0.8 + 0.72 \\ or \: 0.4x = 1.52 \\ or \: x = (1.52)/(0.4) \\ x = 3.8

Answer:

3.8

Explanation:

  • 0.18(5x – 4) = 0.5x + 0.8
  • 0.9x - 0.72= 0.5x +0.8
  • 0.9x- 0.5x= 0.8+0.72
  • 0.4x= 1.52
  • x= 1.52/0.4
  • x= 3.8

----------

  • 0.18(5*3.8 - 4)= 0.5*3.8 + 0.8
  • 0.18*15= 1.9 + 0.8
  • 2.7=2.7
