Answer:

  x = 25

Step-by-step explanation:

This is an ordinary 3-step linear equation. The numbers are all decimals, but that should not be a problem for you. The math works the same as for integers.

  5.5 +0.4x = 6.75 +0.35x

  0.05x +5.5 = 6.75 . . . . . . . . subtract 0.35x

  0.05x = 1.25 . . . . . . . . . . subtract 5.5

  x = 25 . . . . . . . . . . . . divide by 0.05
