    Omkari

    n/2 – 3n/4 + 5n/6 = 21 ⟹ 6n-9n+10n/12 =21 ⟹ 7n/12=21 ⟹ n=21x12/7 ⟹ n=36 To check: n/2 - 3n/4 + 5n/6 = 21 ⟹ 36/2 - 3x36/4 + 5x36/6 =21 ⟹ 18-27+30=21 ⟹ 21=21 ⟹ L.H.S. = R. H. S. Therefore, it is correct. Class 8 Maths Chapter 2 Exercise 2.5 Solution in Video for more answers vist to: https://www.tiwarRead more

    n/2 – 3n/4 + 5n/6 = 21
    ⟹ 6n-9n+10n/12 =21 ⟹ 7n/12=21 ⟹ n=21×12/7 ⟹ n=36
    To check:
    n/2 – 3n/4 + 5n/6 = 21
    ⟹ 36/2 – 3×36/4 + 5×36/6 =21 ⟹ 18-27+30=21 ⟹ 21=21
    ⟹ L.H.S. = R. H. S.
    Therefore, it is correct.

    Solve the following linear equation: x/2 – 1/5 = x/3 + ¼

    Omkari

    x/2 – 1/5 = x/3 + 1/4 ⟹ x/2-x/3 = 1/4+1/5 ⟹ 3x-2x/6 = 5+4/20 ⟹ x/6=9/20 ⟹ x=9x6/20=27/10 To check: x/2-1/5=x/3+1/4 ⟹ 27/10x2 - 1/5 = 27/10x3 + 1/4 ⟹ 27/20 - 1/5 = 9/10 + 1/4 ⟹ 27-4/20 = 18+5/20 ⟹ 23/20 = 23/20 ⟹ L.H.S. = R. H. S. Therefore, it is correct. Class 8 Maths Chapter 2 Exercise 2.5 SolutioRead more

    x/2 – 1/5 = x/3 + 1/4
    ⟹ x/2-x/3 = 1/4+1/5 ⟹ 3x-2x/6 = 5+4/20 ⟹ x/6=9/20 ⟹ x=9×6/20=27/10
    To check:
    x/2-1/5=x/3+1/4
    ⟹ 27/10×2 – 1/5 = 27/10×3 + 1/4 ⟹ 27/20 – 1/5 = 9/10 + 1/4
    ⟹ 27-4/20 = 18+5/20 ⟹ 23/20 = 23/20
    ⟹ L.H.S. = R. H. S.
    Therefore, it is correct.
