Ответ:
2x +9 = 5x -12
(Now bring the x to the left, and rest to the right)
2x -5x = -12 -9
(Solve this)
-3x = -17
Then
: -3 to get x
So -17 : -3 u get 5.67
So
x = 5.67
(I think this would be the answer, if I’m wrong, I’m really sorry)
Ответ:
In the given triangle, AB=BC
Now, 2x+9=5x-12
=> 5x-2x=12+9
=> 3x=21
=> x=21/3
=> x=7
Therefore, the value of x is 7.
