    Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation. 5m=60 (10, 5, 12, 15)

    Aasin

    (a) 5m=60 Putting the given values in L.H.S., 5 x 10 = 50 ∵ L.H.S. ≠ R.H.S. ∴ m=10 is not the solution. 5 x 12 = 60 ∵ L.H.S. = R.H.S. ∴ m =12 is a solution. https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    (a) 5m=60
    Putting the given values in L.H.S.,
    5 x 10 = 50
    ∵ L.H.S. ≠ R.H.S.
    ∴ m=10 is not the solution.
    5 x 12 = 60
    ∵ L.H.S. = R.H.S.
    ∴ m =12 is a solution.

  2. Asked: In:

    State which of the following are equations (with a variable). Given reason for your answer. Identify the variable from the equations with a variable. 17= x+7

    Aasin

    (a) It is an equation of variable as both the sides are equal. The variable is x. https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/
