Exercitiul din imagine! Repedeeee va rogggg! Imi trebuie pana la 17:15.pls repede dau coroanaaaaaaaaaaaaaaaaa ​

Answer 1

$17 \times 2 + 2 \times (120 \div 12 - 2 \times (6 - a \div 6) + 6) = 50$

$34 + 2 \times (10 - 2(6 - \frac{1}{6}a) + 6) = 50$

$34 + 2 \times (10 - 12 + \frac{1}{3}a + 6) = 50$

$34 + 2 \times (4 + \frac{1}{3} a) = 50$

$34 + 8 + \frac{2}{3}a = 50$

$42 + \frac{2}{3}a = 50$

$126 + 2a = 150$

$2a = 150 - 126$

$2a = 24$

$a = 12$
