Question

Solve the equation by trial and error method 3x+6=9+2x

Answer 1

Answer:

x = 3

Step-by-step explanation:

when x = 1

3 + 6 = 9 + 2

9 is not equal to 11  

rejected

when x = 2

6 + 6 = 9 + 4

12 is not equal to 13

rejected

when x = -1

-3 + 6 = 9 - 2

3 is not equal to 7

rejected

when x = 3

9 + 6 = 9 + 6

15 = 15

Therefore ,

x = 3

Answer 2

Answer:

x = 3

Step-by-step explanation:

when x = 1

3 + 6 = 9 + 2

9 is not equal to 11  

rejected

when x = 2

6 + 6 = 9 + 4

12 is not equal to 13

rejected

when x = -1  -3 + 6 = 9 - 2

3 is not equal to 7

rejected

when x = 3

9 + 6 = 9 + 6

15 = 15

Therefore ,

x = 3
