bạn viết thiếu đề rồi, nếu muốn tính x thì bạn phải viết cả kết quả của biểu thức này nữa thì mới tính x được chớ
\(2-\left(5\frac{3}{8}+x-7\frac{5}{24}\right)\)\(:16\frac{2}{3}=0\)
\(\Rightarrow\)\(2-\left(5\frac{3}{8}+x-7\frac{5}{24}\right)=0\)
\(\Rightarrow\)\(5\frac{3}{8}+x-7\frac{5}{24}=2\)
\(\Rightarrow5\frac{3}{8}+x=9\frac{5}{24}\)
\(\Rightarrow x=3\frac{5}{6}\)
( Cách làm thì đúng rồi nhưng đáp án tớ ko chắc chắn )
câu 1 = 0
câu 2 : X=\(\frac{16}{105}\)
X =\(\frac{180}{77}\)
X = 63
(18\(\dfrac{1}{2}+5\dfrac{3}{8}-7\dfrac{5}{24}\)) - 16\(\dfrac{2}{3}\)
=( \(\dfrac{37}{2}\) + \(\dfrac{43}{8}\) - \(\dfrac{171}{24}\) ) - \(\dfrac{50}{3}\)
= \(\dfrac{50}{3}\) - \(\dfrac{50}{3}\)
=0
\(3-\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=2\)
\(3-\left(\frac{43}{8}+x-\frac{173}{24}\right)=2×\frac{50}{3}\)
\(3-\left(\frac{43}{8}+x-\frac{173}{24}\right)=\frac{100}{3}\)
\(\left(\frac{43}{8}+x-\frac{173}{24}\right)=3-\frac{100}{3}\)
\(\left(\frac{43}{8}+x-\frac{173}{24}\right)=-\frac{91}{3}\)
\(\frac{43}{8}+x=-\frac{91}{3}+\frac{173}{24}\)
\(\frac{43}{8}+x=-\frac{185}{8}\)
\(x=-\frac{185}{8}-\frac{43}{8}\)
\(x=-\frac{57}{2}\)
vậy \(x=-\frac{57}{2}\)
nhầm
\(3-\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=2\)
\(\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=3-2\)
\(\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=1\)
\(\left(\frac{43}{8}+x-\frac{173}{24}\right)=1×\frac{50}{3}\)
\(\left(\frac{43}{8}+x-\frac{173}{24}\right)=\frac{50}{3}\)
\(\frac{43}{8}+x=\frac{50}{3}+\frac{173}{24}\)
\(\frac{43}{8}+x=\frac{191}{8}\)
\(x=\frac{191}{8}-\frac{43}{8}\)
\(x=\frac{37}{2}\)
vậy \(x=\frac{37}{2}\)
\(1-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):16\frac{2}{3}=0\)
\(\Rightarrow1-\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=0\)
\(\Rightarrow\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=1\)
\(\Rightarrow\frac{43}{8}+x-\frac{173}{24}=\frac{53}{3}\)
\(\Rightarrow\frac{43}{8}+x=\frac{53}{3}+\frac{173}{24}\)
\(\Rightarrow\frac{43}{8}+x=\frac{199}{8}\)
\(\Rightarrow x=\frac{199}{8}-\frac{43}{8}\)
\(\Rightarrow x=\frac{156}{8}=\frac{39}{2}\)
\(1-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):16\frac{2}{3}=0\)
\(< =>1-\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=0\)
\(< =>1\left(\frac{43}{8}+x-\frac{173}{24}\right)=0\)
\(< =>\frac{43}{8}+x-\frac{173}{24}=0\)
\(< =>\frac{43}{8}+x=\frac{173}{24}\)
\(< =>x=\frac{173}{24}-\frac{43}{8}\)
\(< =>x=\frac{11}{6}\)
x = 0000
phát biểu cảm nghĩ đi
\(3-\left(\frac{5}{\frac{3}{8}}+x-\frac{7}{\frac{5}{24}}\right):\frac{16}{\frac{2}{3}}=2\)
\(\Rightarrow3-\left(\frac{40}{3}+x-\frac{168}{5}\right):24=2\)
\(\Rightarrow\left(-\frac{304}{15}+x\right):24=1\)
\(\Rightarrow\frac{-304}{15}+x=24\)
\(\Rightarrow x=\frac{664}{15}\)
