    Answer: x<2 or xϵ (-∞; 2)

    Step-by-step explanation:

    Add + 3.2x to both sides of inequality:

    2.5-1.2x+3.2x<6.5-3.2x+3.2x

    2.5+2x<6.5

    Deduct 2.5 from both sides of inequality:

    2.5-2.5+2x<6.5-2.5

    2x<4

    Divide both sides of inequality by 2

    2x/2<4/2

    x<2 or xϵ (-∞; 2) (the answer can be written in 2 ways)
