Question

2/3*x+3/4=3

giải giúp mk vs mai mk nộp bài rồi

 

Answer 1

\(\frac{2}{3}\cdot x+\frac{3}{4}=3\)

\(\frac{2}{3}\cdot x=3-\frac{3}{4}\)

\(\frac{2}{3}\cdot x=\frac{12}{4}-\frac{3}{4}\)

\(\frac{2}{3}x=\frac{9}{4}\)

\(x=\frac{9}{4}:\frac{2}{3}\)

\(x=\frac{27}{8}\)

Answer 2

\(\frac{2}{3}\)X+ \(\frac{3}{4}\)= 3.

=> \(\frac{2}{3}\)X= 3- \(\frac{3}{4}\).

=> \(\frac{2}{3}\)X= \(\frac{9}{4}\).

=> X= \(\frac{9}{4}\): \(\frac{2}{3}\).

=> X= \(\frac{27}{8}\).

Vậy X= \(\frac{27}{8}\).

Answer 3

cảm ơn bạn

Answer 4

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

\(\left(=\right)\frac{2}{3x}=\frac{9}{4}\)

\(\left(=\right)2.4=3x.9\)

\(\left(=\right)8=27x\)

\(\left(=\right)x=\frac{8}{27}\)

Answer 5

\(\frac{2}{3}\cdot X+\frac{3}{4}=3\)       

\(\frac{2}{3}\cdot x=3-\frac{3}{4}\)

\(\frac{2}{3}\cdot x=\frac{9}{4}\)

\(x=\frac{9}{4}:\frac{2}{3}\)

\(x=\frac{27}{8}\)

Answer 6

\(\frac{2}{3}.x+\frac{3}{4}=3\)

\(\frac{2}{3}.x=3-\frac{3}{4}\)

\(\frac{2}{3}.x=\frac{9}{4}\)

\(x=\frac{9}{4}:\frac{2}{3}\)

\(x=\frac{27}{8}\)

Answer 7

cảm ơn tát cả mọi người đã giúp mk

Answer 8

có bạn nào ở tỉnh dak nông ko

Answer 9

\(\frac{2}{3}.x+\frac{3}{4}=3\)

\(\frac{2}{3}.x=3-\frac{3}{4}\)

\(\frac{2}{3}x=\frac{9}{4}\)

\(x=\frac{9}{4}\div\frac{2}{3}\)

\(x=\frac{27}{8}\)
