Dau multe puncte si coroana daca raspundeti corect dar daca dati in prostie va dau report!!! Si vreau si rezolvare la a) si b) Multumesc!!!​

Answer 1

Răspuns:

$\bf a)\longrightarrow 3)$

$\bf b)\longrightarrow 1)$

Explicație pas cu pas:

Salutare!

$\bf a) -3x+1=x+13$

$\bf -3x-x+1=13$

$\bf -4x+1=13$

$\bf -4x=13-1$

$\bf -4x=12~~\bigg|:(-4) \implies \boxed{\boxed{\bf x = -3}}$

$\bf a)\longrightarrow 3)$

$\it~~~$

$\bf b)~ 2\sqrt{2}x+\sqrt{8} =\sqrt{2}x+3\sqrt{2}$

$\bf 2\sqrt{2}x+2\sqrt{2} =\sqrt{2}x+3\sqrt{2}$

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

$\bf \sqrt{2}x+2\sqrt{2} =3\sqrt{2}$

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

$\bf \sqrt{2}x=\sqrt{2}~~\bigg|:\sqrt{2}\implies \boxed{\boxed{\bf x=1}}$

$\bf b)\longrightarrow 1)$
