First you have to simplify both sides of the equation.
<span><span><span>
7k</span>−21</span>=<span><span>3k</span>−5
</span></span>Then you subtract 3k from both sides.
<span><span><span><span>7k</span>−21</span>−<span>3k</span></span>=<span><span><span>3k</span>−5</span>−<span>3k </span></span></span><span><span><span>4k</span>−21</span>=<span>−5
</span></span>
Then you Add 21 to both sides.
<span><span><span><span>4k</span>−21</span>+21</span>=<span><span>−5</span>+21</span></span><span><span>4k</span>=16
</span>
And lastly Divide both sides by
4.<span><span><span>4k</span>4</span>=<span>164</span></span><span>k=<span>4
Your answer is : k = 4
