<em>x = - 6</em>
<em>y = - 2</em>
- Step-by-step explanation:
<em>-3x + 5y = 8 | ×(-2)</em>
<em>-2x + 7 y = -2 | ×3</em>
<em />
<em>6x - 10y = - 16</em>
<em>- 6x + 21y = - 6</em>
<em>add</em>
<em>6x - 6x - 10y + 21y = - 16 - 6</em>
<em>11y = - 22</em>
<em>y = - 22 : 11</em>
<em>y = - 2</em>
<em>replace y</em>
<em>- 2x + 7(-2) = - 2</em>
<em>- 2x - 14 = - 2</em>
<em>- 14 + 2 = 2x</em>
<em>2x = - 12</em>
<em>x = - 12 : 2</em>
<em>x = - 6</em>
