This answer can be any real number, as both sides are equal to each other. Try inserting different numbers in here, and you should realize any of them would work
I think you meant to put 3x +7. anyhow, i'll use numbers 1, 2, and 3. that would be 10, 13, and 16.
<span>6+7 (8b+4)
</span><span><span>6+<span><span>(7)</span><span>(<span>8b</span>)</span></span></span>+<span><span>(7)</span><span>(4<span>)
</span></span></span></span><span><span>6+<span>56b</span></span>+<span>28
</span></span>
<span>Combine Like Terms:
</span>
<span>6+<span>56b</span></span>+<span>28
</span>
<span>(<span>56b</span>)</span>+<span>(<span>6+28</span><span>)
