420 + 65 . 4 = ( x + 175 ) : 5 + 30
420 + 260 = ( x + 175 ) : 5 + 30
680 = ( x + 175 ) :5 + 30
\(\Rightarrow\)( x +175 ) : 5 +30 = 680
\(\Rightarrow\)( x + 175 ) :5 = 680 - 30
\(\Rightarrow\)( x + 175 ) : 5 = 650
\(\Rightarrow\)( x + 175 ) = 650 . 5
\(\Rightarrow\)x + 175 = 3250
\(\Rightarrow\)x = 3250 - 175
\(\Rightarrow\)x = 3075
( X + 175 ) : 5 + 30 = 420 + 65 x 4
420+65*4=(x+175)/5+30
tìm x
420 + 65 x 4 = ( x + 175) : 5 + 10
420 + 65 . 4 = ( x + 175 ) : 5 + 30
(32.15) : 2 = (x + 70) : 14 - 40
x - 4867 = ( 175 . 2050 . 76) + 25 + 23
giup em a
x -48 . ( 120 .5 .14 ) : 60 + 25
420 + 65 .4 = ( x + 175 ):5 + 30
ai làm nhanh mình tick nhé
(52 x X +175):5+30=420 + 65 x 4 Tìm x
Làm giúp nha ! hứa thick ạk
a. 420 + 65 .4 = ( x + 175 ) : 5 + 30
[(x+32)-17].2=42
b. ( 32.15) : 2 = ( x+70): 14-40
[ 61 + ( 53-x)] .17=1785
Tìm x :
a) 13 - 2 ( x + 1 ) = 7
b) 6x + 2 . 4 = 5^2 . 2
c) 420 + 65 . 4 = ( x + 175 ) : 5 + 30
d) 32 . 12 : 2 = ( x + 70 ) : 14 - 40
e) 231 - ( x - 6 ) = 1339 : 13
f) 10 + 2x = 4^5 : 4
g) 70 - 5 ( x - 3 ) = 45
Ai làm đúng cho 5 tick nha ai nhanh thì ok
Tìm x biết :
a) 420 + 65 .4 = ( x+ 175 ) : 51 + 30
b) ( 32 . 15 ) : 2 = ( x + 70 ) : 14 - 40
Ai giải nhanh đúng tick cho 5 tick thề lun đó
