194 – 24 : ( 12 : 3 × x – 3 ) – 25 = 145
194 – 24 : ( 12 : 3 × x – 3 ) = 145 + 25
194 – 24 : ( 12 : 3 × x – 3 ) = 170
24 : ( 12 : 3 × x – 3 ) = 194 – 170
24 : ( 12 : 3 × x – 3 ) = 24
12 : 3 × x – 3 = 24 : 24
12 : 3 × x – 3 = 1
12 : 3 × x = 3 + 1
12 : 3 × x =4
3 × x = 12 : 4
3 × x = 3
x = 3 : 3
x =1

$194 – 24 : (12 : 3 × x – 3) – 25 = 145$
$⇔194 – 24 : (4 × x – 3) = 145 + 25$
$⇔ 194 – 24 : (4 × x – 3) = 170$
$⇔24 : (4 × x – 3) = 194 – 170$
$⇔24 : (4 × x – 3) = 24$
$⇔ 4 × x – 3 = 24 : 24$
$⇔ 4 × x – 3 = 1$
$⇔ 4 × x = 1 + 3$
$⇔4 × x = 4$
$⇔ x = 4 : 4$
$⇔x = 1$
Vậy$ x = 1$
