\(\left|x+74\right|-\left|-318\right|=\left|-20\right|\)
\(\left|x+74\right|-318=20\)
\(\left|x+74\right|=20+318=338\)
\(\Rightarrow\hept{\begin{cases}x+74=338\\x+74=-338\end{cases}}\Rightarrow\hept{\begin{cases}x=264\\x=-412\end{cases}}\)
\(318-5\left(x-64\right)=103\)
\(\Rightarrow5\left(x-64\right)=318-103\)
\(\Rightarrow5\left(x-64\right)=215\)
\(\Rightarrow x-64=43\)
\(\Rightarrow x=43+64\)
\(\Rightarrow x=107\)
_____________
\(4^x\cdot5+216=296\)
\(\Rightarrow4^x\cdot5=296-216\)
\(\Rightarrow4^x\cdot5-80\)
\(\Rightarrow4^x=16\)
\(\Rightarrow4^x=4^2\)
\(\Rightarrow x=2\)
___________
\(376-6^x:3=364\)
\(\Rightarrow6^x:3=376-364\)
\(\Rightarrow6^x:3=12\)
\(\Rightarrow6^x=36\)
\(\Rightarrow6^x=6^2\)
\(\Rightarrow x=2\)
___________
\(\left(4x-1\right)^2=121\)
\(\Rightarrow\left(4x-1\right)^2=11^2\)
\(\Rightarrow\left[{}\begin{matrix}4x-1=11\\4x-1=-11\end{matrix}\right.\)
\(\Rightarrow\left[{}\begin{matrix}4x=12\\4x=-10\end{matrix}\right.\)
\(\Rightarrow\left[{}\begin{matrix}x=3\\x=-\dfrac{5}{2}\end{matrix}\right.\)
a ) ( x + 74 ) - 318 = 200
x + 74 = 200 + 318
x + 74 = 518
x = 518 - 74
x = 444
b ) 3636 : ( 12 . x - 91 ) = 36
12 . x - 91 = 3636 : 36
12 . x - 91 = 101
12 . x = 101 + 91
12 . x = 192
x = 192 : 12
x = 16
c ) ( x : 23 + 45 ) . 67 = 8911
x : 23 + 45 = 8911 : 67
x : 23 + 45 = 133
x : 23 = 133 - 45
x : 23 = 88
x = 88 . 23
x = 2024
d ) ( 3 . x - 6 ) + 57 = 60
3 . x - 6 = 60 - 57
3 . x - 6 = 3
3 . x = 3 + 6
3 . x = 9
x = 9 : 3
x = 3
\(a)\) \(\left(x+74\right)-318=200\)
\(x+74=518\)
\(x=444\)
Vậy x = 444
\(b)\) \(3636:\left(12x-91\right)=36\)
\(12x-91=101\)
\(12x=192\)
\(x=16\)
Vậy x = 16
\(c)\) \(\left(x:23+45\right)67=8911\)
\(x:23+45=133\)
\(x:23=88\)
\(x=2024\)
Vậy x = 2024
\(d)\left(3x-6\right)+57=60\)
\(3x-6=3\)
\(3x=9\)
\(x=3\)
Vậy x = 3
( x + 74 ) + 318 = 200
x + 74 = 200 - 318
x + 74 = -118
x = - 118 - 74
x = -192
( x + 74 ) + 318 = 200
x + 74 = 200 - 318
x + 74 = -118
x = -118 - 74
x = -192
1/53+-1/106+-1/159=|x|/318
6/318+-3/318+-2/318=|x|/318
1/318=|x|/318
=>|x|=1
x=1 hoặc x=-1
ta có : (x+74)-318=280
(x+74) =280+318
X+74 =598
x =598-74
x =524
ta có : 3628 : ( 12*x-91)=36
12*x-91 =3628:36
12*x-91 =907/9
12*x =1726/9
x =1726/9:12
x =863/54
ta có : (x:23+45) *67= 8911
x:23+45 =8911:67
x:23+45 = 133
x:23 =133-45
x:23 =88
x =88*23
x =2024
chúc em may mắn nhá!!!
Câu a:
(x+74) = 280 + 318
x+74 = 598
x = 598 - 74
x = 524
Đáp số: 524
318-x:6=20
x:6=318-20
x:6=298
x=298*6
x=1788
318-x:6=20
x:6=318-20
x:6=298
x=298x6
x=1788
