Question

a–2=6,Solve the given equation by trial and error method.

Answer 1

a-2 = 6
when a=1 we get
1-2=6
-1=6
when a=4 we get
4-2=6
2=6
when a=8 we get
8-2=6
6=6
.*. LHS=RHS
THE VALUE OF a=8 :)

Answer 2

Answer:

Trial and error method means to use the different values and see if the equation satisfies in both sides of it.

Step-by-step explanation:

By trial and error method, we will check different values of a amd try to solve this equation.

let us take a=1 ,

1-2 = 6

-1 is not equal to 6 so a=1 is not correct

let us take a=2

2-2=6

0 is not equal to 6 so a= 2 is not correct

let us take a higher value that is a=7,

7-2= 5

so 5 is not equal to 6

so a=5 is not correct

let take a= 8

8-2= 6

here we get the answer so a= 8 is correct value.
