<em>Answer:</em>
<em>y = - 5 ; x = 6</em>
<em>Step-by-step explanation:</em>
<em>-5y+4x= 49</em>
<em>7y+2x= -23 | × - 2</em>
<em />
<em>-5y+4x= 49</em>
<em>-14y - 4x = 46</em>
<em>___________ +</em>
<em>- 5y - 14y + 4x - 4x = 49 + 46</em>
<em>- 19y = 95 | × - 1</em>
<em>19y = - 95</em>
<em>y = - 95 : 19</em>
<em>y = - 5</em>
<em />
<em>- 5(-5) + 4x = 49</em>
<em>25 + 4x = 49</em>
<em>4x = 49 - 25</em>
<em>4x = 24</em>
<em>x = 24 : 4</em>
<em>x = 6</em>
Answer:
8/x = x/20
x^2=160
