Question

Rezolvati si explicati-mi va rog.​

Answer 1

Răspuns:

5+4·{7-2·[-2⁰+3·(x+2)]}=17

4·{7-2·[-2⁰+3·(x+2)]}=17-5

7-2·[-2⁰+3·(x+2)]=12:4

-2·[-2⁰+3·(x+2)]=3-7

-1+3·(x+2)=4:2

3·(x+2)=2+1

x+2=3:3

x=1-2

x=-1

Answer 2

Răspuns:

x = -1

Explicație pas cu pas:

$5 + 4 \cdot \Big\{7 - 2 \cdot \Big[ - {2}^{0} + 3 \cdot \Big(x + 2\Big) \Big] \Big\} = 17$

$4 \cdot \Big\{7 - 2 \cdot \Big[ - 1 + 3 \cdot \Big(x + 2\Big) \Big] \Big\} = 17 - 5$

$7 - 2 \cdot \Big[ - 1 + 3 \cdot \Big(x + 2\Big) \Big] = 12 : 4$

$7 - 2 \cdot \Big[ - 1 + 3 \cdot \Big(x + 2\Big) \Big] = 3$

$2 \cdot \Big[ - 1 + 3 \cdot \Big(x + 2\Big) \Big] = 7 - 3$

$- 1 + 3 \cdot \Big(x + 2\Big) = 4 : 2$

$3 \cdot \Big(x + 2\Big) = 2 + 1$

$x + 2 = 3 : 3$

$x = 1 - 2$

$\implies x = - 1$
