a) X - 33 = 124= b) 5. X =495 C) 2.X + 6 = 30 d) x:9+4 = 31=X e) x2 + 100 = 181 =​

Answer 1

Respuesta:

$a) \: \: x - 33 = 124 \\ x = 124 + 33 = \\ x = 157$

$b) \: \: \: 5x = 495 \\ 5x \div 5 = 495 \div 5 = \\ x = 99$

$c) \: \: 2x + 6 = 30 \\ 2x + 6 = 30 \\ 2x = 30 - 6 \\ 2x = 24 = \\ x = 12$

$d) \: \: x9 + 4 = 31 = \\ 9x + 4 = 31 \\ 9 x = 31 - 4 \\ 9x = 27 = \\ x = 3$

$e) \: \: x2 + 100 = 181 = \\ 2x + 100 = 181 \\ 2x = 181 - 100 \\ 2x = 81 \\ x = \frac{81}{2}$
