−<span>3<span>(<span>x−<span>2y</span></span>) = </span></span><span>(<span>−3</span>)</span><span>(<span>x+<span>−<span>2y</span></span></span><span>) </span></span> And then...
(−3)(x+−2y) = <span><span>(<span>−3</span>)</span><span>(x)</span></span>+<span><span>(<span>−3</span>)</span><span>(<span>−<span>2y</span></span><span>) </span></span></span> which equates to <span>−<span>3x</span></span>+<span>6<span>y
The answer of which you're looking for is </span></span><span>−<span>3x</span></span>+<span>6<span>y.</span></span>
