tim x biet: 5*x-3*(4*x-2*(4*x-3*(5*x-2)))=182
Tim x biet 2.(x-3)-3.(x-1)-5
Đề thiếu rồi. Bằng bao nhiêu nữa mới tìm x được
tim x biet
x-3/x+5=5/7
Ta có: \(\frac{x-3}{x+5}=\frac{5}{7}\)
\(\Rightarrow7.\left(x-3\right)=5.\left(x+5\right)\)
\(\Rightarrow7x-21=5x+25\)
\(\Rightarrow7x-5x=21+25=46\)
\(\Rightarrow2x=46\)
\(\Rightarrow x=46:2=23\)
Vậy x = 23
Ủng hộ mik nha!
tim x biet x.3+5.x=16
\(x.3+5.x=16\)
\(\Rightarrow x.\left(3+5\right)=16\)
\(\Rightarrow x.8=16\)
\(\Rightarrow x=\frac{16}{8}\)
\(\Rightarrow x=2\)
vậy \(x=2\)
\(x.3+5.x=16\)
\(\left(3+5\right).x=16\)
\(8.x16\)
\(x=16:8\)
\(x=2\)
X x 3 + 5 x X = 16
X x ( 3 + 5 ) = 16
X x 8 = 16
X = 16 : 8
X = 2
tim x biet : /x+5/+/3-x/=8
Tim x, biet : 5/4 nhan x = 5/8 + 3/12
tim x biet 3(x-5)-2(2x-3)+ 3(6-x)=17
\(3\left(x-5\right)-2\left(2x-3\right)+3\left(6-x\right)=17\)
\(\Rightarrow3x-15-4x+6+18-3x=17\)
\(\Rightarrow-4x=8\)
\(\Rightarrow x=-2\)
Vậy x = -2
tim x biet 3(x-5)-2(2x-3) 3(6-x)=17
a, tim x€Z biet (x-6) chia het cho (x-5)
b, tim x€Z, y€Z biet (x-1).(xy-5)=5
