Question

1,    1/2x+150%x=2014

2, 1/2x+1/8x=3/4

 nhớ giải ra rõ ràng

Answer 1

1) Ta có : 1/2x+150%x=2014 suy ra (1/2+150/100)*x=2014 =(0,5+1,5)*x=2014=2*x=2014 

Suy ra x=2014/2=1007

2)

1/2x+1/8x=3/4

=(1/2+1/8)x=3/4

=(0,5+0,125)x=0,75

=0,625x=0,75 suy ra x=1,2

Nho k nha

Answer 2

a)\(\frac{1}{2}x+150\text{%}.x=2014\)

\(\frac{1}{2}x+\frac{3}{2}x=2014\)

\(x.\left(\frac{1}{2}+\frac{3}{2}\right)=2014\)

\(x.2=2014\)

\(x=2014:2=1007\)

b) \(\frac{1}{2}x+\frac{1}{8}x=\frac{3}{4}\)

  \(x.\left(\frac{1}{2}+\frac{1}{8}\right)=\frac{3}{4}\)

                  \(x.\frac{5}{8}=\frac{3}{4}\)

       \(x=\frac{3}{4}:\frac{5}{8}=\frac{6}{5}\)
