( 32. 15) : 2 = ( x - 70) . 14 - 40
240 = ( x- 70). 14 - 40
240+40 = (x-70).14
280 = ( x- 70).14
280:14 = x- 70
20 = x - 70
20+70 = x
90 = x hay x= 90
k mik nhaaaaaaaaaaaaaaaaa
\(\frac{\Rightarrow480}{2}=14x-980-40\)
\(\Leftrightarrow240+1020=14x\)
\(\Leftrightarrow x=\frac{1260}{14}=90\)

a) 195 - x: 17 = 125
x : 17 = 195 - 125 = 70
x = 70 . 17
x = 1190
b) 32 . 15 : 2 = (x + 70) : 14 - 40
240 = ( x + 70) : 14 - 40
(x + 70) : 14 = 280
x + 70 = 280 . 14 = 3920
x = 3920 - 70
x = 3850
A)195-x:17=125
=\(x:17=195-125\)
\(x:17=70\)
\(x=70.17\)
=>x=\(1190\)
B) 32.15:2=(x+70):14-40
\(\text{B) 32.15:2=(x+70):14-40}\)
\(=480:2=\left(x+70\right):14-40\)
\(=\left(x+70\right):14-40=240\)
\(=\left(x+70\right):14=240+40\)
\(\left(x+70\right):14=280\)
=>\(x+70=280.14\)
\(x+70=3920\)
=> x=\(3920-70\)
=>x=\(3850\)

( x + 70 ) : 14 - 40 = (32 . 15 ) : 2
( x + 70 ) : 14 - 40 = 240
( x + 70 ) : 14 = 240 + 40 = 280
x + 70 = 280 x 14 = 3920
x = 3920 - 70
x = 3850
Vậy x = 3850.
(x+70):14-40=(32.15):2
(x+70):14-40=480;2
(x+70):14-40=240

(x+70):14 =302,5
x+70 =302,5*14
x+70 =4235
x+70
còn lại tự làm nha nhok
