Answer

$y=\dfrac{5}{3}x-5$

Work Step by Step

Using the properties of equality, in terms of $ y ,$ the given equation, $ \dfrac{2}{3}x-\dfrac{2}{5}y=2 ,$ is equivalent to \begin{array}{l}\require{cancel} 15\left(\dfrac{2}{3}x-\dfrac{2}{5}y\right)=(2)15 \\\\ 5(2x)-3(2y)=30 \\\\ 10x-6y=30 \\\\ -6y=-10x+30 \\\\ y=\dfrac{-10}{-6}x+\dfrac{30}{-6} \\\\ y=\dfrac{5}{3}x-5 .\end{array}
