Question

solve the following equation by trial and error method 5x = 2 x + 9
​

Answer 1

Explanation:

5x = 2x + 9

5x + 2x = 9

7x = 9

x = 9/7

Answer 2

Answer:

3

Explanation:

In hit and trial method we try to solve a ques with different numbers so let us try with 2

If we put 2 in place of X in the equation the equation will be

5(2)=2(2)+9

10=4+9

10≠13

LHS ≠RHS

this is not the answer so let's try 3

The equation will be

5(3)=2(3)+9

5*3=2*3+9

15= 6+9

15=15

LHS=RHS

hence verified
