Question

A- x2/3 + 3 - 2x = 0 C- x+1/2 - x2 + 1/3 = 0 D- x2 /2 - 1/5 = 3x-1/5

Answer 1

Resposta:

a)

$x \frac{2}{3} + 3 - 2x = 0 \\ \frac{2}{3} x + 3 - 2x = 0 \\ 2x + 9 - 6x = 0 \\ - 4x + 9 = 0 \\ - 4x = - 9 \\ x = \frac{9}{4}$

c)

$x + \frac{1}{2} - x2 + \frac{1}{3} = 0 \\ \frac{5}{6} = 0$

d)

$x \frac{2}{2} - \frac{1}{5} = 3x - \frac{1}{5} \\ x.1 = 3x \\ x = 3x \\ x - 3x = 0 \\ - 2x = 0 \\ x = 0$

Answer 2

Resposta:

3x−1÷5.....
