<PRE><B>Question 536929</B>
The point has to be on both lines.  Use the first equation to find a, the y coordinate.&lt;P&gt;
Assuming that the second equation is supposed to be y + (2/3)x = b.  If it is as written in the problem, it doesn&#39;t show what it equals and there&#39;s no way to determine b.
Substitute 3 for x.&lt;P&gt;
-4(3)+2y=8&lt;P&gt;
-12 + 2y = 8&lt;P&gt;
Add 12 to both sides.&lt;P&gt;
2y = 20&lt;P&gt;
Divide both sides by 2.&lt;P&gt;
y=10&lt;P&gt;
So the point is (3,10)&lt;P&gt;
Plug that point into the second equation to find b.&lt;P&gt;
10 + (2/3)3 = b = 10+2 =12
