Question

Tìm x,y,z biết :

b) \(x\cdot\left(x-\frac{3}{2}\right)=0\)

c)\(|\frac{1}{4}-x|+\frac{2}{3}=\frac{1}{2}\)

d)\(|3\cdot x-2|=|x+1|\)

e)\(|x+\frac{3}{4}|+|x-y|=0\)

g)\(|4\cdot x-2|-2\cdot x=\frac{3}{4}\)

h)\(|5\cdot x+1|-2\cdot x=1\)

i)\((x-\frac{3}{2})\cdot\left(2\cdot x+1\right)>0\)

k)\(|x+\frac{1}{2}|+|x+y+z|+|\frac{1}{3}+y|=0\)

l)\(|2\cdot x-\frac{1}{2}|-\frac{1}{4}=3\)

GIÚP MK VS, CẢM ƠN MỌI NGƯỜI RẤT NHÌU !!!

Answer 1

lam sao bạn viết chữ to như 3/4 . ( x + 1/2 ) vậy
