Question

solve the following equation by trial and error method. a-2=6. 5m=15​

Answer 1

Answer:

1)a-2=6

let a be 5

5(a)-2=3

3 is not equal to 6

let a be 6

6 - 2=3

3 is not equal to 6

let a be 7

7-2=5

5 is not equal to 6

let a be 8

8-2=6

a=8

2)let m be 1

5*1=5

5 is not equal 1

let m be 2

5*2= 10

10 is not equal to 15

let m be 3

5*3=15

15=15

so, m=3
