Answer:
x=0, y=-5. (0, -5).
Step-by-step explanation:
5x-6y=30
-6y=30
-----------

5x-6(-5)=30
5x+30=30
5x=30-30
5x=0
x=0/5
x=0
We would be solving you equation step by step.
<span><span>96<span>(<span>70n</span>)</span></span>=<span><span><span>(96)</span><span>(70)</span></span><span>(28)
</span></span></span>Step 1: Simplify both sides of the equation.
<span><span>6,720n</span>=188,160
</span>Step 2: Divide both sides by 6720.
<span><span><span>6720n/</span>6720</span>=<span>188160/6720</span></span><span>n=28
</span><u>Answer:</u><span>n=<span>28</span></span>
