Question

Pick out the solution from the values given in the bracket next to each equation. Show other do not satisfy the equation 5m/2- 4=1 (1, 2, -2, -1) 2.

​

Answer 1

Answer:

5m=60

Putting the given values in L.H.S.,

5 x 10 = 50, 5 x 5 = 25

∵ L.H.S. ≠ R.H.S. ∵ L.H.S.≠ R.H.S.

∴m=10 is not the solution. ∴m=5 is not the solution.

5 x 12 = 60, 5 x 15 = 75

∵ L.H.S. = R.H.S. ∵ L.H.S. ≠ R.H.S.

∴m=12 is a solution. ∴m=15 is not the solution.
