Question

3(x+4)-6=9. Find the value of x​

Answer 1

3(x-4)-6 = 9

___________

3x - 12 = 9 + 6

3x = 9 + 6 + 12

x = 27/3

_____________

x = 9

Answer 2

Given,

3(x+4)-6 = 9

3x+12-6 = 9

3x+6 = 9

3x = 9-6

3x = 3

x = 3/3

x = 1

Verification: substitute the value of x in the equation.

3(1+4)-6 = 9

3(5)-6 = 9

15-6 = 9

9 = 9

Therefore the value of x is 1.
