\(\left(x+1\right)\left(xy-3\right)=3\)
\(\Leftrightarrow\left(x+1;xy-3\right)\in\left\{\left(1;3\right);\left(3;1\right);\left(-1;-3\right);\left(-3;-1\right)\right\}\)
hay \(\left(x,y\right)\in\left\{\left(2;2\right);\left(-2;0\right);\left(-4;-\dfrac{1}{2}\right)\right\}\)
(x+1)(xy-1)=3
Tim X :
a)x:1/3+2/3[1/5-1] =4
b)1/2 [x-3/5]=-1/3[7/6-3/2]
c)1/3-3/4=3/5 -x
d)4/7x-2/3=1/3+x
Tìm x biết :
a) -2×(x-1/3)-5× (x+1/3)=1/2×x
b) -(1/2×x-3/4)-(-x+1)=-3/2
Cảm ơn nhiều nha!
1.(-86-x)-(3+2x)=-4-15
2.18+(-x)-(40-28)=-32-(-18)
3.-27-(-31+x)-25=-5-17
4.-9-14-x+42)-38=-5+13
45-(-x+1)+50=2x-5+37
Tìm các số nguyên x biết :
a) 73 - 3x = 5.(1 - x) + 8 b) /2 - x/ + 1 = 3^5 : 3^3
\(\left(x-2\right)^3+\frac{8}{27}=0\)
\(4\frac{1}{3}:\frac{x}{4}=6:0,3\)
(0,25-30%x).\(\frac{1}{3}-\frac{1}{4}=5\frac{1}{6}\)
\(\frac{x-2}{\frac{-2}{9}}=\frac{-2}{x-2}\)
A. 5x=6×(x-1)
B.1×(3x)=(x+1)×2
C.3×(2x+1)=5×(x+2)
D.5×(7-x)=-4×(8x-2)
Cho x1 + x2 +x3+..........+x2016 + x2017 = 0 và x1 + x2 = x3 + x4 = x5 + x6 = .......... = x2015 +x2016 = x2016 + x2017 = 1
Tìm x2016
Tìm x
/x/ + / x+1 / + / x+4 / +....+ | x + 20| -11x = 0
| x - 7 | + | y + 11 | = 2
|6-x| + |y+2| = 1
| x+1| + / x+2 / + / x+3 / +....+ | x + 10| =11x
Giúp tớ với ạ 😭
