1. m – m-1/2 = (1)- m-2/3 ⟹ m/1 - m-1/2 + m-2/3 = 1 ⟹ 6m-3(m-1)+2(m-2)/6 =1 ⟹ 6m-3m+3+2m-4/6 = 1 ⟹ 5m-1/6 =1 ⟹ 5m-1=6 ⟹ 5m+6+1 ⟹ 5m=7 ⟹ m=7/5 Class 8 Maths Chapter 2 Exercise 2.5 Solution in Video for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-8/maths/chapter-2/

    m – m-1/2 = (1)- m-2/3
    ⟹ m/1 – m-1/2 + m-2/3 = 1 ⟹ 6m-3(m-1)+2(m-2)/6 =1
    ⟹ 6m-3m+3+2m-4/6 = 1 ⟹ 5m-1/6 =1 ⟹ 5m-1=6
    ⟹ 5m+6+1 ⟹ 5m=7 ⟹ m=7/5

  2. 3t-2/4 – 2t+3/3 = 2/3 – t ⟹ 3t-2/4 - 2t+3/3 + t=2/3 ⟹ 3(3t-2)-4(2t+3)+12t/12 = 2/3 ⟹ 9t-6-8t-12+12t/12 = 2/3 ⟹ 13t-18/12 = 2/3 ⟹ 3x(13t-18)=2 x 12 ⟹ 39t-54=24 ⟹ 39t=24+54 ⟹ 39t=78 ⟹ t=78/39=2 To check: 3t-2/4 – 2t+3/3 = 2/3 – t ⟹ 3X2-2/4 - 2x2+3/3 = 2/3 -2 ⟹ 6-2/4 - 4+3/3 = 2-6/3 ⟹ 4/4 - 7/3 = -4/3Read more

    3t-2/4 – 2t+3/3 = 2/3 – t
    ⟹ 3t-2/4 – 2t+3/3 + t=2/3 ⟹ 3(3t-2)-4(2t+3)+12t/12 = 2/3
    ⟹ 9t-6-8t-12+12t/12 = 2/3 ⟹ 13t-18/12 = 2/3
    ⟹ 3x(13t-18)=2 x 12 ⟹ 39t-54=24 ⟹ 39t=24+54
    ⟹ 39t=78 ⟹ t=78/39=2
    To check:
    3t-2/4 – 2t+3/3 = 2/3 – t
    ⟹ 3X2-2/4 – 2×2+3/3 = 2/3 -2 ⟹ 6-2/4 – 4+3/3 = 2-6/3
    ⟹ 4/4 – 7/3 = -4/3 ⟹ 1/1-7/3=-4/3
    ⟹ 3-7/3 = -4/3 ⟹ -4/3 = -4/3
    ⟹ L.H.S. = R. H. S. Therefore, it is correct.

    x-5/3 = x-3/5

    ⟹ 5X(x-5) =3 (x-3) ⟹ 5x-25=3x-9
    ⟹ 5x-3x= -9+25 ⟹ 2x=16 ⟹ x=16/2=8
    To check:
    x-5/3 = x-3/5
    ⟹ 8-5/3 = 8-3/5 ⟹ 3/3=5/5 ⟹ 1 = 1
    ⟹ L.H.S. = R. H. S
    Therefore, it is correct.

    x+7 – 8x/3 = 17/6 – 5x/2
    ⟹ x/1 – 8x/3 + 5x/2 = 17/6 – 7/1 ⟹ 6x-16x+15x/6 = 17-42/6
    ⟹ 5x/6 = -25/6 ⟹ x= -25×6/6×5 ⟹ x=-5
    To check:
    x+7 – 8x/3 = 17/6 – 5x/2
    ⟹ -5+7- 8x(-5)/3 = 17/6 – 5x(-5)/2 ⟹ 2+ 40/3=17/6+25/2
    ⟹ 6+40/3 = 17+75/6 ⟹ 46/3 = 92/6 ⟹ 46/3=46/3
    ⟹ L.H.S. = R. H. S.
    Therefore, it is correct.
