Question

05(2x - 3) + 3(5x-6) + 13 = 8(3x + 7)-63; A​

Answer 1

Răspuns: $\bf \red{\underline{x = 13}}$

Explicație pas cu pas:

$\bf 5\cdot\big(2x - 3\big) + 3\cdot\big(5x-6\big) + 13 = 8\cdot\big(3x + 7\big)-63$

$\bf 10x - 15 + 15x-18+ 13 = 24x + 56-63$

$\bf 25x - 15 -18+ 13 = 24x + 56-63$

$\bf 25x - 33+ 13 = 24x + 56-63$

$\bf 25x - 20 = 24x + 56-63$

$\bf 25x = 24x + 56-63+20$

$\bf 25x = 24x + 76-63$

$\bf 25x = 24x + 13$

$\bf 25x-24x = 13$

$\bf \red{\underline{x = 13}}$
