Question

"2x - 1/3 (x+12) = 10" find x​

Answer 1

The value of x  are 05.005 and -12.005.

Step-by-step explanation:

Given:

$2x -\frac{1}{3( x+12)} =10$

To Find:

The value of  x.

Solution :

As given-    $2x -\frac{1}{3( x+12)} =10$

$2x -\frac{1}{3( x+12)} =10$

$6x(x+12)-1=30(x+12)$

$6x^{2} +72x-1=30x+360$

$6x^{2} +42x-361=0$

$x^{2} + 7x - 60.16 =0$

$x= \frac{-7+/- \sqrt{(7)^{2} - 4 \times 1\times (-60.16 )} }{2\times1}$

$x=\frac{-7+/-17.01}{2}$

$x=5.005 \ and - 12.005$

Thus,the value of x  are  5.005 and -12.005
