Question

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) 

Answer 1

5m = 60 

m = 12 is a solution to the given equation because for m = 12,

5m = 5 × 12 = 60 and hence, the equation is satisfied.

m = 10 is not a solution to the given equation because for m = 10,

5m = 5 × 10 = 50 and not 60

m = 5 is not a solution to the given equation because for m = 5,

5m = 5 × 5 = 25 and not 60

m = 15 is not a solution to the given equation because for m = 15,

5m = 5 × 15 = 75 and not 60
