Question

$\frac{3 \times }{5} - \frac{8}{3} = 7$

​

Answer 1

Respuesta:

x=145/9

Explicación paso a paso:

$\frac{3x}{5} - \frac{8}{3} = 7$

$\frac{3x}{5} \times \frac{3}{3} = \frac{9x}{15} \\ \frac{8}{3} \times \frac{5}{5} = \frac{40}{5} \\ \frac{7}{1} \times \frac{15}{15} = \frac{105}{15}$

lo que da equivalente

$\frac{9x}{15} - \frac{40}{15} = \frac{105}{15} \\ 9x - 40 = 105 \\ 9x = 105 + 40 \\ 9x = 145 \\ x = \frac{145}{9}$
