Question

Calcule o valor de x na equação 4x/6 + (-2x-3)/3 =11-4x no conjunto dos números reais

Answer 1

$\frac{4}{6}x + \frac{(-2x + 3)}{3} = 11 - 4x\\\frac{2}{3}x + \frac{(-2x + 3)}{3} = 11 - 4x\\3.(\frac{2}{3}x + \frac{(-2x + 3)}{3}) =3.( 11 - 4x)\\2x + (-2x + 3) = 33 - 12x\\2x - 2x + 3 = 33 - 12x\\3 = 33 - 12x\\-12x = 3 - 33\\-12x = -30\\12x = 30\\2x = 5\\x = \frac{5}{2}$

Answer 2

Resposta:

x = 3

Explicação passo-a-passo:

$\frac{4x}{6} + \frac{-2x - 3}{3} = 11 - 4x\\\\4x + 2 (-2x - 3) = 66 - 24x\\\\4x - 4x - 6 = 66 - 24x\\\\- 6 = 66 - 24x\\\\24x = 66+6\\\\24x = 72\\\\x = 3$
