2x – 6y = 12
for x = 1
2 - 6y = 12
y = -10/6
y = -5/3
For x = 2
4 – 6y = 12
y = -8/6
y = -4/3
For x = 3
6 – 6y = 12
<span>y = -1</span><span>
<span><span>
<span>
Hence
x =
</span>
</span>
<span>
<span>
1 then y = -5/3
</span></span><span>x = 2 then y = -4/3
</span><span>x = 3 then y = -1</span></span></span>
