$$6(x+4)+3(x-4)+2(x+2)=50$$
$x = \frac{34}{11} = 3\frac{1}{11} \approx 3.090909091$
$$6x+24+3\left(x-4\right)+2\left(x+2\right)=50$$
$$6x+24+3x-12+2\left(x+2\right)=50$$
$$9x+24-12+2\left(x+2\right)=50$$
$$9x+12+2\left(x+2\right)=50$$
$$9x+12+2x+4=50$$
$$11x+12+4=50$$
$$11x+16=50$$
$$11x=50-16$$
$$11x=34$$
$$x=\frac{34}{11}$$
