Question

Найдите корень уравнения

2x+3/3-5x+13/6+5-2x/2=6

Answer 1

$frac{2x + 3}{3} - frac{5x + 13}{6} + frac{5 - 2x}{2} = 6$
$frac{(2x + 3)2 - (5x + 13) + (5 - 2x)3}{6} = 6 times 6$
$(4x + 6) - (5x + 13) + (15 - 6x) = 36$
$4x + 6 - 5x - 13 + 15 - 6x = 36$
$- 7x + 8 = 36$
$- 7x = 36 - 8$
$- 7x = 28$
$x = frac{ 28}{ - 7}$
$x = - 4$
