Answer

$x=-5$

Work Step by Step

We are given that $3(x-2)+5x=6x-16$. In order to solve for x, we must first simplify the left side using the distributive property. $3x-6+5x=6x-16$ Group like terms on the left side. $8x-6=6x-16$ Add 16 to both sides. $8x+10=6x$ Subtract 8x from both sides. $10=-2x$ Divide both sides by -2. $x=-5$
