¡Hola!

Explicación paso a paso:

☁️Tema: Ecuaciones☁️

$a) \: 6x + 16 = 46 \\ 6x = 46 - 16 \\ 6x = 30 \\ x = 30 \div 6 \\ x = 5$

$b) \: (x + 12).3 = 66 \\ 3x + 36 = 66 \\ 3x = 66 - 36 \\ 3x = 30 \\ x = 30 \div 3 \\ x = 10$

$c) 15 = x : 5 + 10 \\ 15 - 10 = x \div 5 \\ 5 = x \div 5 \\ 5 \times 5 = x \\ 25 = x$

$d) \: 9x − 15 = 12 \\ 9x = 12 + 15 \\ 9x = 27 \\ x = 27 \div 9 \\ x = 3$

$e) \: (x − 8).3 = 36 \\ 3x - 24 = 36 \\ 3x = 36 +24 \\ 3x = 60 \\ x = 60 \div 3 \\ x = 20$

$f) \: x \div 12 + 3 = 5 \\ x \div 12 = 5 - 3 \\ x \div 12 = 2 \\ x = 2 \times 12 \\ x = 24$

$g) 50 = 11x + 17 \\ 50 - 17 = 11x \\ 33 = 11x \\ 33 \div 11 = x \\ 3 = x$

$i) x \div 10 − 2 = 8 \\ x \div 10 = 8 + 2 \\ x \div 10 = 10 \\ x = 10 \times 10 \\ x = 100$
