Question

bài tìm x

a) 435 - ( x + 16 ) = 425 : 17

b) ( x + 4/3 ) * 7/4 = 5 - 7/6

Answer 1

a) \(435-\left(x+16\right)=425:17\)

\(435-\left(x+16\right)=25\)

\(\Rightarrow x+16=435-25=410\)

\(\Rightarrow x=410-16=394\)

b) \(\left(x+\frac{4}{3}\right)\cdot\frac{7}{4}=5-\frac{7}{6}\)

\(\left(x+\frac{4}{3}\right)\cdot\frac{7}{4}=\frac{23}{6}\)

\(\Rightarrow x+\frac{4}{3}=\frac{23}{6}:\frac{7}{4}=\frac{46}{21}\)

\(\Rightarrow x=\frac{46}{21}-\frac{4}{3}=\frac{6}{7}\)

Answer 2

a) 435 - ( x + 16 ) = 25

x+ 16 = 435 - 25

x + 16 = 410

x = 410 - 16

x = 394

b) (x+4/3 ) * 7/4 = 23/6

x+4/3= 23/6 : 7/4

x+4/3 = 46/21

x = 46/21  - 4/3

x = 6/7

Answer 3

435-(x+16)=425:17

435-(x+16)=25

       x+16 =435-25

       x+16 =410

       x       =394

b) \(\left(x+\frac{4}{3}\right)\times\frac{7}{4}=5-\frac{7}{6}\)

    \(\left(x+\frac{4}{3}\right)\times\frac{7}{4}=\frac{23}{6}\)

               \(\left(x+\frac{4}{3}\right)=\frac{23}{6}:\frac{7}{4}\)

                \(\left(x+\frac{4}{3}\right)=\frac{46}{21}\)

                                \(x=\frac{46}{21}-\frac{4}{3}\)

                                 \(x=\frac{6}{7}\)

T mk nha bạn ^...^ !!!

Answer 4

a) 435 - ( X + 16 ) = 425 : 17

   435 - ( X + 16 ) = 25

             X + 16 = 410

                X     = 410 - 16

                X     = 394

b) \(\left(X+\frac{4}{3}\right)x\frac{7}{4}=5-\frac{7}{6}\)

    \(\left(X+\frac{4}{3}\right)x\frac{7}{4}=\frac{23}{6}\)

      \(X+\frac{4}{3}=\frac{23}{6}:\frac{7}{4}\)

      \(X+\frac{4}{3}=\frac{46}{21}\)

     \(X=\frac{46}{21}-\frac{4}{3}\)

    \(X=\frac{6}{7}\)
