Question

If m is a whole number less than 5, complete the table and by inspection of the table, find the solution of the equation 2m – 5 = – 1 :

Answer 1

Answer:

2m-5=-1

if we put m=2

then,

2(2)-5=4-5=-1

hence m =2 is the solution of 2m-5=-1

now table

if m=0

2m-5=2(0)-5=-5

if m=1

2m-5=2(1)-5=-3

if m=2

2m-5=-1

if m=3

2m-5=2(3)-5=1

now you put this in the table
