<p>let the function g be defined by g(x)=2x-3. if g(k)=g(2k-3), what is the value of g(4k)?...</p>
<p>nvm...............</p>
<p>I guess not the best way to solve this problem, but here it is:</p>
<p>If g(k)=g(2k-3), then k is equal to 3. (3=6-3)</p>
<p>So, the value of g(4k) is g(12)=24-3=21</p>
<p>2k-3= 2(2k-3)-3
2k-3=4k-6-3
2k-3=4k-9
2k-6=0......x4
8k-24=0
8k-3-21=0
8k-3=21</p>
