124 : x cộng 24 :x trừ 48 :xbằng 25
Tìm X biết: 124 : X + 24 : X – 48 : X = 25.
124 : x + 24 : x - 48: x = 25
( 124 + 24 - 48 ) : x = 25
100 : x = 25
x = 4
\(124\div x+24\div x-48\div x=25\)
\(\Leftrightarrow\left(124+24-48\right)\div x=25\)
\(\Leftrightarrow100\div x=25\)
\(\Leftrightarrow x=100\div25=4\)
124/x + 24/x - 48/x =25
=>(124 + 24 - 48)/x=25
=>100/x=25
=>x=4
Tìm x .
48 : 24 - x = 1. 124 -2 × ( x + 3 ) = 24
`#3107.101107`
\(48\div24-x=1\\ \Rightarrow2-x=1\\ \Rightarrow x=2-1\\ \Rightarrow x=1\)
Vậy, `x = 1`
____
\(124-2\times\left(x+3\right)=24\\ \Rightarrow2\left(x+3\right)=124-24\\ \Rightarrow2\left(x+3\right)=100\\ \Rightarrow x+3=100\div2\\ \Rightarrow x+3=50\\ \Rightarrow x=50-3\\ \Rightarrow x=47\)
Vậy, `x = 47.`
1) 48 : 24 - x = 1 2) 123 - 2 x (x+3) = 24
2-x=1 2 x (x+3) = 123 - 24
x= 2-1 2 x (x+3) = 99
x= 1 x+3 = 99 : 2
x+3 = \(\dfrac{99}{2}\)
x = \(\dfrac{99}{2}\) -3
x = \(\dfrac{93}{2}\)
(124 cộng 118 trừ x )=217
124 + 118 - x = 217
118 - x = 217 - 124
118 - x =93
x= 118-93
x=25
hok tốt nha
124 + 118 - x = 217
118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25

124 x 25 + 24 x 124 + 50 + 124
= 124 x 25 + 50 ( 24 + 1 )
= 124 x ( 25 + 50 + 25 )
= 124 x 100

Câu 1: Tìm x
a, x x 124 + 5276 = 48304 b, x x 45 - 3209 = 13036
x : 125 x 64 = 4608 x : 48 : 25 = 374
trl sẽ có like
a)x.124+5276=48304
=>x.124=43028
=>x=347
x:125.64=4608
=>x:125=72
=>x=9000
b)x.45-3209=13036
=>x.45=16245
=>x=361
x:48:25=374
=>x:48=9350
=>x=448800
a:
\(x\times124+5276=48304\\ \Rightarrow x\times124=43028\\ \Rightarrow x=347\\ x:125\times64=4608\\ \Rightarrow x:125=72\\ \Rightarrow x=9000\)
b:
\(x\times45-3209=13036\\ \Rightarrow x\times45=16245\\ \Rightarrow x=361\\ x:48:25=374\\ \Rightarrow x:48=9350\\ \Rightarrow x=448800\)
151 x 24 – 48 x 13 –24 x 25 sosssss
\(151\times24-48\times13-24\times25\\ =151\times24-24\times2\times13-24\times25\\ =151\times24-24\times26-24\times25\\ =24\times\left(151-26-25\right)\\ =24\times100\\ =2400\)
151 x 24 - 48 x 13 - 24 x 25
= 3624 - 624 - 600
= 3000 - 600
= 2400
âm2x trừ mở ngoặc x trừ 17 đóng ngoặc bằng 34 trừ mở ngoặc am x cộng 25 đóng ngoặc
-2x - (x-17) = 34 - (-x+25)
-2x-x+17 = 34+x-25
-3x+17 = x+9
-3x-x = 9-17
-4x = -8
x = -8 : (-4)
x = 2
vậy____
-2x-(x-17)=34-(-x+25)
=> -2x-x+17=34+x-25
=> -3x+17=x+9
=> -3x-x=9-17
= -4x=-8 => x=2
