Answer:

use addition and substraction method:

[tex] \frac{x + 3}{2} = \frac{3x + 5}{5} [/tex]

[tex] \frac{x + 3}{2} - \frac{3 x + 5}{5} = 0 [/tex]

[tex] \frac{5(x + 3)}{5(2)} - \frac{2(3x + 5)}{2(5)} = 0[/tex]

[tex] \frac{5x + 15 - 6x - 10}{10} = 0[/tex]

[tex]5x + 15 - 6x - 10 = 0[/tex]

[tex] - x + 5 = 0[/tex]

[tex] - x = - 5[/tex]

[tex]x = \frac{ - 5}{ - 1} [/tex]

[tex]x = 5[/tex]
