Answer
$x=-4$
Work Step by Step
$8x-(3x+2)=3x-10$ $\longrightarrow$ distributive property
$8x-3x-2=3x-10$ $\longrightarrow$ combine like terms
$5x-2=3x-10$ $\longrightarrow$ addition property of equality
$5x-2+2-3x=3x-10+2-3x$ $\longrightarrow$ combine like terms
$2x=-8$ $\longrightarrow$ multiplication property of equality
$2x\div2=-8\div2$ $\longrightarrow$ simplify
$x=-4$
