Answer 1

a)

1. 2x+2=3

2. 6-6y=9

b)

1. √3×x+√2=0

2. √5×x-√7=8

Answer 2

Explicație pas cu pas:

a)

1.

$3x + 3 = 0 \iff 3x = - 3 \\ x = - \frac{3}{3} \implies x = - 1$

2.

$- 5x - 5 = 0 \iff - 5x = 5 \\ x = - \frac{5}{5} \implies x = - 1$

b)

1.

$\sqrt{3}x + \sqrt{2} = 0 \iff \sqrt{3} x = - \sqrt{2} \\ x = - \frac{^{ \sqrt{3} )} \sqrt{2} }{ \sqrt{3} } \implies x = - \frac{ \sqrt{6} }{3}$

2.

$- \sqrt{6}x + \sqrt{3} = 0 \iff - \sqrt{6} x = - \sqrt{3} \\ x = \frac{^{ \sqrt{6} )} \sqrt{3} }{ \sqrt{6} } \iff x = \frac{ \sqrt{18} }{6} \\ \implies x = \frac{ 3\sqrt{2} }{2}$
