x- 32:16=48

=>x-2=48

=>x=48+2

=>x=50

(x-32):16=48

=>x-32= 48x 16

=>x-32= 768

=>x=768+32

=>x=800

1.x=50

2.x=bấm máy tính nhá mik hơi bí chút

k ủng hộ nhá

1. x-32:16=48

         x-32=48.16

        x-32=768

            x=768+32

             x=800

Vậy x=800

2.(x-32):16=48

Tương tự như câu trên nha bn

*** mk nha

\(\left(x+\dfrac{1}{3}\right)\times\dfrac{9}{14}\times\dfrac{7}{3}-\dfrac{1}{3}=1:\dfrac{9}{5}\\ \Rightarrow\left(x+\dfrac{1}{3}\right)\times\dfrac{3}{2}-\dfrac{1}{3}=\dfrac{5}{9}\\ \Rightarrow\left(x+\dfrac{1}{3}\right)\times\dfrac{3}{2}=\dfrac{5}{9}+\dfrac{1}{3}\\ \Rightarrow\left(x+\dfrac{1}{3}\right)\times\dfrac{3}{2}=\dfrac{8}{9}\\ \Rightarrow x+\dfrac{1}{3}=\dfrac{8}{9}:\dfrac{3}{2}\\ \Rightarrow x+\dfrac{1}{3}=\dfrac{16}{27}\\ \Rightarrow x=\dfrac{16}{27}-\dfrac{1}{3}\\ \Rightarrow x=\dfrac{7}{27}\)

 18 . ( x-16 ) = 18 

x-16 = 18 : 18 

x- 16 = 1

x= 16+1

x= 17 

18 (x - 16) = 18

18 (x - 16) = 18 . 1

Vì 18 = 18 

=> x - 16 = 1

=> x = 17

Vậy x = 17.

    Bài làm :

Ta có :

18 (x - 16) = 18

<=> x - 16 = 1

=> x = 17

Vậy x = 17

4/5 + 3/15 = 1

2/3 + 32/24 = 2

5/6 + 15/18 = 5/3

k nhé:))

\(\frac{4}{5}+\frac{3}{15}=\frac{4}{5}+\frac{1}{5}=\frac{4+1}{5}=\frac{5}{5}=1\)

\(\frac{2}{3}+\frac{32}{24}=\frac{2}{3}+\frac{4}{3}=\frac{2+4}{3}=\frac{6}{3}=2\)

\(\frac{5}{6}+\frac{15}{18}=\frac{5}{6}+\frac{5}{6}=\frac{5+5}{6}=\frac{10}{6}\)

\(50\%+\dfrac{1}{2}+\dfrac{1}{7}\times\dfrac{2}{5}+\dfrac{1}{7}\times\dfrac{3}{5}\)

\(=\dfrac{1}{2}+\dfrac{1}{2}+\dfrac{2}{35}+\dfrac{3}{35}\)

\(=1+\dfrac{5}{35}\)

\(=1+\dfrac{1}{7}\)

\(=\dfrac{8}{7}\)

\(50\%+\dfrac{1}{2}+\dfrac{1}{7}x\dfrac{2}{5}+\dfrac{1}{7}x\dfrac{3}{5}\)

\(=\dfrac{1}{2}+\dfrac{1}{2}+\dfrac{1}{7}x\left(\dfrac{2}{5}+\dfrac{3}{5}\right)\)

\(=1+\dfrac{1}{7}x1\)

\(=\dfrac{7}{7}+\dfrac{1}{7}=\dfrac{8}{7}\)

50% + 1/2 + 1/7 × 2/5 + 1/7 × 3/5

= 1/2 + 1/2 + 1/7 × (2/5 + 3/5)

= 1 + 1/7 × 1

= 1 + 1/7

= 7/7 + 1/7

= 8/7

8/7
