Answer:

x = 15/7

Step-by-step explanation:

Divide both side by 15 we get 5x + 3x = 15x-15

-7x=-15 divide by -7 and we get x = 15/7

Answer:

[tex] \frac{x}{3} + \frac{x}{5} = x - 1 \\ \frac{3x + 5x}{3 \times 5} = x - 1 \\ \frac{8x}{15} = x - 1 \\ 8x = 15(x - 1) \\ 8x = 15x - 15 \\ 15x - 8x = 15 \\ 7x = 15 \\ x = \frac{15}{7} \\ [/tex]
