Question

7,52 x-10=0,52 x + 5
7:34x - 20 = 0,34 x + 10​

Answer 1

Explicación paso a paso:

$7,52 x-10=0,52 x + 5 \\ 7x = 5 + 10 \\ x = \frac{15}{7}$

$7:34x - 20 = 0,34 x + 10 \\ \frac{7}{34}x - 20 = \frac{17}{50} x + 10 \\ 175x - 17000 = 289x + 8500 \\ - 114x = 25500 \\ x = \frac{25500}{114} \\ x = \frac{4250}{19}$
