C)6=x-0,5
D)3√2=x+2√2
E)0,(5)=5/9-x
Rezolvare, nu doar calcul
Si repede, va rog!

Answer 1

$a)2 \sqrt{3} x - \sqrt{3} = 0$

$2 \sqrt{3} x = \sqrt{3} \: | \div \sqrt{3}$

$2x = 1$

$x = \frac{1}{2}$

$b)( \sqrt{5} + 1) \times x = 1 + \sqrt{5}$

$( \sqrt{5} + 1) \times x = \sqrt{5} + 1 \: | \div ( \sqrt{5} + 1)$

$x = 1$

$c)6 = x - 0.5$

$x = 6 + 0.5$

$x = 6.5$

$d)3 \sqrt{2} = x + 2 \sqrt{2}$

$x = 3 \sqrt{2} - 2 \sqrt{2}$

$x = \sqrt{2}$

$e)0.(5) = \frac{5}{9} - x$

$\frac{5}{9} = \frac{5}{9} - x$

$- x = \frac{5}{9} - \frac{5}{9}$

$- x = 0$

$x = 0$
