(x+4)/ (x+2) = 3/2
2x+8=3x+6
x=2
[tex]\it\dfrac{x+4}{x+2}=\dfrac{3}{2} \Leftrightarrow \dfrac{x+4-x-2}{x+2}=\dfrac{3-2}{2} \Leftrightarrow \dfrac{2}{x+2}=\dfrac{1}{2} \Leftrightarrow \\ \\ \Leftrightarrow \it \dfrac{2}{x+2-2}=\dfrac{1}{2-1} \Leftrightarrow \dfrac{2}{x} =1 \Leftrightarrow x = 2 [/tex]
