1. 0,7x - 1 = 0,3 + 22. 0,13x = 0,07x - 0,3jawab pakai cara ya-!!

1. 0,7x – 1 = 0,3 + 22. 0,13x = 0,07x – 0,3jawab pakai cara ya-!!

Jawaban:

$1. : x = frac{33}{7}$

$2. : x = - 5$

Penjelasan dengan langkah-langkah:

$1. : 0.7x - 1 = 0.3 + 2$

$0.7x = 0.3 + 2 + 1$

$frac{7}{10}x = frac{3}{10} + 3$

$frac{7}{10} x = 3 frac{3}{10}$

$frac{7}{10} x = frac{33}{10}$

$x = frac{33}{10} times frac{10}{7}$

$x = frac{33}{7}$

$2. : 0.13x = 0.07x - 0.3$

$0.13x - 0.07x = - 0.3$

$0.06x = - 0.3$

$frac{6}{100}x = - frac{3}{10}$

$x = - frac{3}{10} times frac{100}{6}$

$x = - frac{10}{2}$

$x = - 5$
