Question

c)3/2x-0,5=0;dau coroanaaa!!!
d) 3(x-1)+5=6x+4
e) x√3-1/√3=0 ajutor si explicatie

Answer 1

a)
$\frac{3}{2} x - \frac{1}{2} = 0 \\ \frac{3}{2} x = \frac{1}{2} \\ x = 3$
b)

$3(x + 1) + 5 = 6x + 4 \\ 3x + 3 + 5 = 6x + 4 \\ 3x - 6x = 4 - 3 - 3 \\ - 3x = - 2 \\ x = \frac{2}{3}$
c)
$\frac{x \sqrt{3 - 1} }{ \sqrt{3} } = 0 \\ x \sqrt{3 - 1} = 0 \\ x = 0 \div \sqrt{3 - 1} \\ x = 0$
