what is the solution for t in the solution?

[tex]\\ \sf\longmapsto \dfrac{2}{3}t-\dfrac{1}{5}t=2[/tex]
[tex]\\ \sf\longmapsto (\dfrac{2}{3}-\dfrac{1}{5})t=2[/tex]
[tex]\\ \sf\longmapsto (\dfrac{10-3}{15})t=2[/tex]
[tex]\\ \sf\longmapsto \dfrac{7}{15}t=2[/tex]
[tex]\\ \sf\longmapsto t=\dfrac{30}{7}[/tex]
