    Answer:

    n=1.5

    Step-by-step explanation:

    distribute: 1.2n-5.4= 3.4-2(3n-1)

    Add numbers]: 1.2 n – 5.4= 5.4-6n

    Move terms: 1.2n+6n- 5.4=5.4

    Add like terms: 7.2n= 5.4+5.4

    Divide both sides of equation by 7.2

    Answer n= 1.5

    Answer:

    n = 1.5

    Step-by-step explanation:

    here’s the solution :-

    =》0.6 (2n – 9) = 3.4 – 2 (3n- 1)

    =》1.2n – 5.4 = 3.4 – 6n + 2

    =》1.2n + 6n = 5.4 + 5.4

    =》7.2n = 10.8

    =》n = 10.8 ÷ 7.2

    =》n = 1.5
