Question

ache o valor do x. a) x + 12=26, b) x - 184=142, c) 2x + 16=40, d) x - 4=62​

Answer 1

Resposta:

$a) \: x + 12 = 26 \\ x = 26 - 12 \\ x = 14$

$b) \: x - 184 = 142 \\ x = 142 + 184 \\ x = 326$

$c) \: 2x + 16 = 40 \\ 2x = 40 - 16 \\ 2x = 24 \div (2) \\ x = 12$

$d) \: x - 4 = 62 \\ x = 62 + 4 \\ x = 66$
