if P(xp,yp) divides a line segment from A(x1,y1) to B(x2,y2) in the ratio 2/3, then:
[tex]\begin{gathered} xp=x1+\frac{2}{3}(x2-x1) \\ yp=y1+\frac{2}{3}(y2-y1) \end{gathered}[/tex]Since we only need to find the x coordinate:
[tex]\begin{gathered} (x1,y1)=(0,0) \\ (x2,y2)=(4,3) \\ xp=0+\frac{2}{3}(4-0) \\ xp=2.667 \\ x\approx2.7 \end{gathered}[/tex]
