If <em>y</em> = <em>x</em> and <em>y</em> = <em>z</em>, then by substitution we can say <em>x</em> = <em>z</em>.
In this case, substitution gives us
-1/2 <em>x</em> - 2 = -3/2 <em>x</em> + 2
and we can solve for <em>x</em> :
3/2 <em>x</em> - 1/2 <em>x</em> = 2 + 2
<em>x</em> = 4
then solve for <em>y</em> :
<em>y</em> = -1/2 <em>x</em> - 2
<em>y</em> = -1/2 * 4 - 2
<em>y</em> = -2 - 2
<em>y</em> = -4
