Question

a) (x+2/3)=1/6

b) (x-3/4)+1=1 và 2/3

c) (x)-1=(-1/4)

giải giúp em với

 

 

Answer 1

\(x+\frac{2}{3}=\frac{1}{6}\)

\(x=\frac{1}{6}-\frac{4}{6}\)

\(x=-\frac{3}{6}=-\frac{1}{2}\)

Answer 2

a) (x+2/3)=1/6

=>x=1/6-2/3

=>x=-1/2

b) (x-3/4)+1= 1 và 2/3

=> (x-3/4)+1=5/3

=> x-3/4 =2/3

=> x=17/12

c, (x)-1=(-1/4)

=>x=-1/4+1

=>x=3/4

Answer 3

a)   \(X+\frac{2}{3}=\frac{1}{6}\)

=>\(X=\frac{1}{6}-\frac{2}{3}=\frac{1}{6}-\frac{4}{6}=\frac{-3}{6}=\frac{-1}{2}=-0.5\)

b)   \(\left(X-\frac{3}{4}\right)+1=1\)

=>\(X-\frac{3}{4}=0\)

=>\(X=\frac{3}{4}\)

   \(\left(X-\frac{3}{4}\right)+1=\frac{2}{3}\)

=>\(X-\frac{3}{4}=-\frac{1}{3}\)

=>\(X=\frac{5}{12}\)

c)    \(X-1=-\frac{1}{4}\)

\(X=-\frac{1}{4}+1=\frac{3}{4}\)
