Question

(3 x a + 2) : 4 - 2 = 3 pls repede ​

Answer 1

Răspuns:

$\purple{ \bf a = 6}$

Explicație pas cu pas:

$\bf(3 \cdot a + 2) : 4 - 2 = 3$

$\bf(3 \cdot a + 2) : 4 = 3 + 2$

$\bf(3 \cdot a + 2) : 4 = 5 \: \: \: \bigg| \cdot4$

$\bf 3 \cdot a + 2 = 20$

$\bf 3 \cdot a = 20-2$

$\bf 3 \cdot a = 18 \: \: \: \bigg| : 3$

$\red{ \boxed{\bf a = 6}}$

Answer 2

Buna! :)

( 3 × a + 2 ) : 4 - 2 = 3

( 3 × a + 2 ) : 4 = 3 + 2

( 3 × a + 2 ) : 4 = 5 | × 4

__________________

3 × a + 2 = 20

3 × a = 20 - 2

3 × a = 18 | : 3

a = 6

Sper ca am fost de ajutor ! ♡︎
