/17-x/=4
/x/=17-4
/x/=13
=>x=13 hoặc x=-13
tick cho mk nha bạn
Ta co : |17 - x| = 4
=> 17 - x = + 4
* TH1 : 17 - x = 4
=> x = 17 - 4 = 13
* TH2 : 17 - x = -4
=> x = 17 - (-4)
=> x = 21
Vay x = 13 hoac 21
4/9 x (-13/-17) + (-2/17) x 4/9 + 2/9 x 4/17 = ?
Tìm x
1.-9/46 - 4/1/23 : (3/1/4 - x : 3/5) + 2/8/23=1
2.(6/2/7 * x +3/7) : 2/1/5 - 3/7=-1
3.5/8/17 : x + (-1/17) : x + 3/1/17 : 17/1/3=4/17
4.1/1 * 4 + 1/4 * 7 + 1/7 * 10 + ...+ 1/x(x + 3)=6/19
Tìm x:
a)5/8/17:x+(-4/17):x+3/1/7:17/1/3=4/11
b)|x|-5/3/7|x|-3/4=2|x|+(-8/7)
tìm x, biết : | x + 11/17 | + | x + 2/17 | + | x + 4/17 | = 4x
-4/13 x 5/17 + -12/13 x 4/17 + 4/13
93/17:x+(-4/17):x+22/7:52/3=4/11
A) 4-(12-17)=17-(x-4+15)
B) 14-(12-x)=4-(15-13)
Tìm x, biết
93/17 : x + -4/17 : x + 22/7 : 52/3 = 4/11
Tìm x biết
\(5\frac{8}{17}:x+\frac{-4}{17}:x+3\frac{1}{7}:17\frac{1}{3}=\frac{4}{11}\)
4 ^ 2 x 4 ^ 17 : 4 ^ 10
8 ^ 12 : 8 ^ 9 x 8 ^ 13
2 ^ 17 x 3 x 7 : 2 ^ 13
