\(5\frac{4}{7}\) + ( x-2 ) x 1/3 = \(17\frac{3}{4}\)
39/7 + ( x- 2 ) x 1/3 = 71/4
( x -2 ) x 1/3 = 71/4 - 39/7
( x -2 ) x 1/3 = 341/28
x - 2 = 341/28 : 1/3
x -2 = 341/28 x 3
x -2 = 1023/28
x = 1023/28 + 2
x = 1079/28
P/s : số lớn tek!?
Cbht!!!!!
\(\frac{\frac{5}{4}}{7}+\left(x-2\right)\times\frac{1}{3}=\frac{\frac{17}{3}}{4}\)
\(\frac{35}{4}+\left(x-2\right)\times\frac{1}{3}=\frac{68}{3}\)
\(\frac{35}{4}+\left(x-2\right)=68\)
\(x-2=68-8,75\)
\(x-2=59,25\)
\(x=59,25+2\)
\(x=61,25\)
5/4/7 + ( x - 2 ) x 1/ 3 = 17 / 3 / 4
35/4 + ( x - 2 ) x 1/3 = 68/3
( x -2 ) x 1/3 = 68/3 - 35/4
( x-2 ) x 1/3 = 167 / 12
x - 2 = 167 / 12 : 1/ 3
x -2 = 167 / 4
x = 167 / 4 + 2
x = 175/4 .
Nhớ giữ lời hứa đó k mình 6 k đều lên điểm nha
