Let's solve for x.
<span><span><span>3x</span>+y</span>=<span>−4
</span></span>Step 1: Add -y to both sides.
<span><span><span><span>3x</span>+y</span>+<span>−y</span></span>=<span><span>−4</span>+<span>−y
</span></span></span><span><span>3x</span>=<span><span>−y</span>−4
</span></span>Step 2: Divide both sides by 3.
<span><span><span>3x/</span>3</span>=<span><span><span>−y</span>−4/</span><span>3</span></span></span>
x=<span><span><span>−1/3</span>y</span>+<span>−4/3</span></span>
