Question 510275
Add the two equations:

<table>
<tr><td>&nbsp;<td>5x<td>-2y<td>=<td>4</tr>
<tr><td>+&nbsp;<td>1x<td>+2y<td>=<td>8</tr>
<tr><td>&nbsp;<td>6x<td>+0y<td>=<td>12</tr>
</table>
.
6x =12
.
Solve for 'x'
x = 2
.
substitute x=2 to find y
.
5(2) -2y = 4
-2y = -6
y = 3
.
check this answer using the other equation
.
x + 2y = 8 ??
2 + 2(3) = 8
correct.
.
Answer: x =2 and y = 3
.
Done.
