<span>6x + 12y = 11
</span><span>4x + 8y = 3. 
</span>6x=−12y+11 

<span>4x+8y=3 </span>
<span>6x=11−12y </span>
4x+8y=3
<span>6x/6 =11/6 −12y/6 </span>
<span>4x+8y=3 </span>
<span>x=11/6−12y/6 </span>
<span>4x+8y=3 </span>
<span>x=11/6 −2y </span>
<span>4x+8y=3 </span>
<span>value substituted is 11/6 −2y. </span>
<span>x=11/6 −2y </span>
<span>4(11/6 −2y)+8y=3 </span>
<span>x=11/6 −2y </span>
<span>22/3 −8y+8y=3 </span>
<span>x=11/6 −2y </span>
<span>22/3 =3 </span>
<span>Since 22/3 ≠3, there are no solutions.
</span>hope this helps
