<PRE><B>Question 68696</B>
7x+3(2x+5)=10x+17
7x+6x+15=10x+17
13x+15=10x+17
-15 -15
13x=10x+2
-10 -10  &lt;&lt;&lt;&lt;&lt;&lt; instead of add -10, you will add -10x
&lt;br&gt;&lt;br&gt;
13x = 10x + 2
-10x  -10x
3x = 2  &lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt; divide both side by 3 to solve for x.
x = 2/3
