Metoda mersului invers[12+3·(2x+1)]=24

Răspuns :

Salut !

[tex][12 + 3 \times (2x + 1)] = 24[/tex]

[tex]3 \times (2x + 1) = 24 - 12[/tex]

[tex]3 \times (2x + 1) = 12[/tex]

[tex]2x + 1 = 12:3[/tex]

[tex]2x + 1 = 4[/tex]

[tex]2x = 4 - 1[/tex]

[tex]2x = 3[/tex]

[tex] = > x = \frac{3}{2} [/tex]
