Explicação passo a passo:
[tex]\mathsf{\dfrac{3x - 5}{2} - \dfrac{x - 2}{5} = 7}[/tex]
[tex]\mathsf{\dfrac{15x - 25}{10} - \dfrac{2x - 4}{10} = \dfrac{70}{10}}[/tex]
[tex]\mathsf{15x - 25 - (2x - 4) = 70}[/tex]
[tex]\mathsf{15x - 25 - 2x + 4 = 70}[/tex]
[tex]\mathsf{13x - 21 = 70}[/tex]
[tex]\mathsf{13x = 91}[/tex]
[tex]\boxed{\boxed{\mathsf{x = 7}}}[/tex]
