Tìm x y biết
a;|x-3|+(3y-1)^2018=0
b(2x-1)^2+|2y-x|-8=12-5x2^2
c (x-2017)^x+1-(x-2017)^x+11=0
Tìm GTNN
2) B= /3x-1/+/4y+2/-3x
3) C= /2x-1/+/2x+5/+2017
4) D= /x+3/+/2x-1/+/x-1/
Tìm x biết : \(|\left|3x-3\right|+2x+\left(-1\right)^{2016}|=3x+2017^0\)
Tìm x, y
| x - 2017 | + | y - 2018 | ≤ 0
3| x - y |5 + 10| y + 2/3 |7 ≤ 0
1/2(3/4x - 1/2)2018 + 2017/2018|4/5 y+ 6/25| ≤ 0
2017 |2x - y | 2018 + 2018 | y - 4 |2017 ≤ 0
Tìm GTNN:
a)A=|x+1|+|x+2|+|+x+3|+...+|x+2016|+100
b)B=|x+1|+|x+2|+|+x+3|+...+|x+2016|+|x+2017|+100
c)C=|5x+3|+|2x-2|-x+1
Tìm x:
a) \(2017-\left|x-2017\right|=x\)
b) \(\left|2x-3\right|+\left|2x+4\right|=7\)
tim x , biet :
1 ) 2017 - \ x - 2017 \ = x
2) -1/2 . ( 3x - 1 ) + 3/4 . ( 3-2x) = -3 . ( x/2 - 1 ) - ( 4/5) mu -1
a,Tìm x biết: ||3x-3|+2x+(-1)2016 |=3x+20170
b,Cho B= 1+ 1/2*(1+2)+1/3*(1+2+3)+1/4*(1+2+3+4)+...+1/x*(1+2+3+...+x)
Tìm số nguyên dương x để B= 115
Tìm x,y biết:
a) (x+y)2018 + 2017.| y-1 | = 0
b) ( x - 1)2 + ( y + 3)2 = 0
c) 2017. |2x - y|2018 + 2018. | y- 4| 2017 = 0
d) ( x + y)2018 + 2017. | y - 1 | = 0
Giúp mik gấp ạ!!!
