Question

Tìm x: 

(4/3 + x) × 7/4 = 5 - 7/6

Answer 1

(4/3 + x) × 7/4 = 5 - 7/6

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

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

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

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

\(x=\frac{23}{14}\)

Answer 2

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

    (4/3+x=23/6:7/4

     (4/3+x)=46/21

        x=46/21- 4/3

         x=6/7

Answer 3

(4/3+x)x7/4=23/6

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

4/3+x=46/21

x=46/21-4/3=6/7

Answer 4

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

(4/3+ x)          =  23/6 :7/4

(4/3 +x )         = 46/21

x                    = 46/21- 4/3

x                    = 6/7

Answer 5

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

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

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

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

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

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