cần câu trả lời gấp, ai nhanh mik tick cho ạ
\(1) 420+65.4=(x+175):5+30\)
\(\implies 420+260=(x+175):5+30\)
\(\implies 680=(x+175):5+30\)
\(\implies 650=(x+175):5\)
\(\implies 650.5-175=x\)
\(\implies 3075=x\)
\(2)x-4867=(175.2050.70):25+23\)
\(\implies x-4867=1004500+23\)
\(\implies x-4867=1004523\)
\(\implies x=1009390\)
\(3) 134-[(96-7x):4-2]=126\)
\(\implies (96-7x):4-2=8\)
\(\implies(96-7x):4=10\)
\(\implies 96-7x=40\)
\(\implies 7x=56\)
\(\implies x=8\)
\(4) 4-\{100-[(100-5x):8-5]:10\}:25=0\)
\(\implies 4-\{100-[(100-5x):8-5]:10\}=0\)
\(\implies 100-[(100-5x):8-5]:10=4\)
\(\implies 100-[(100-5x):8-5]=40\)
\(\implies (100-5x):8-5=60\)
\(\implies (100-5x):8=65\)
\(\implies 100-5x=520\)
\(\implies 5x=-420\)
\(\implies x=-84\)

Tính bằng cách thuận tiện nhất:
a) 4 x 6 x 5 c) 2 x 175 x 5
b) 2 x 6 x 5 d) 6 x 4 x 25
( X + 175 ) : 5 + 30 = 420 + 65 x 4
( X + 175 ) : 5 + 30 =420 + 65 x 4
( X + 175 ) : 5 + 30 = 680
( X + 175 ) : 5 = 680 - 30 = 650
( X + 175 ) = 650 x 5 = 3250
X = 3250 - 175 = 3075

420 + 65 . 4 = ( x + 175 ) : 5 + 30
(32.15) : 2 = (x + 70) : 14 - 40
x - 4867 = ( 175 . 2050 . 76) + 25 + 23
giup em a
420 + 65 . 4 = ( x + 175 ) : 5 + 30
=> ( x + 175 ) : 5 + 30 = 420 + 45 . 4
=> ( x + 175 ) : 5 + 30 = 600
=> ( x + 175 ) : 5 = 600 - 30
=> ( x + 175 ) : 5 = 570
=> x + 175 = 570 . 5
=> x + 175 = 2850
=> x = 2850 - 175
=> x = 2675

X + 56 x 2 - [ 32+16 x3 : 6-15 ] = 0
420 +65 x 4 =[ X +175 ] : 5 +30
X - 4867 = [ 175 x 2050 x 70 ] : 25 +23
2436 : x =12
THU GỌN BIỂU THỨC
a) - ( 4 - x ) + ( 15 - 25 )
b)( a+ 175 ) - ( 175 - 53 ) - ( 53 - 157 )
c)( x -127 ) - ( 123 - x )+ ( - 250 )
d)( x-2 ) - ( 5 -x ) + ( 7 - x )
a) - ( 4 - x ) + ( 15 - 25 )
= - 4 + x + 15 - 25
= - 14 + x
