<u>Answer:</u>
<em>First Equation → </em><u><em>y = 21/4</em></u>
<em>Second Equation → </em><u><em>x = -1/57</em></u>
<u />
<u>Explanation:</u>
<em>solving equation #1</em>
<em></em>
step 1 - simplify
<em></em>
step 3 - multiply each side of the equation by six
step 4 - add three to both sides of the equation.
step 5 - add three y to both sides of the equation.
step 6 - simplify
step 7 - divide both sides of the equation by four
Therefore, the solution to the first given equation is <u><em>y = 21/4 </em></u><em>or y = 5.25.</em>
