Answer:

The value of $x=-4$ . The figure is also attached below.

Step-by-step explanation:

Considering the expression

$5x + 6(x - 2) - 8 (x - 3)$

If we have to find the vale of $x$ , then

$5x + 6(x - 2) - 8 (x - 3)=0$

$5x+6x-12-8\left(x-3\right)=0$

$5x+6x-12-8x+24=0$

$3x+12=0$

$\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}$

$3x+12-12=0-12$

$3x=-12$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3x}{3}=\frac{-12}{3}$

$x=-4$

Therefore, the value of $x=-4$ . The figure is also attached below.

If you're born on June 9th in 1993, on June 9th in 2015 you would have your 22nd birthday (2015-1993=22).

So you're 22 years old, and, as of today, 17 days tool (22 years 17 days).
