x/3 + 15/26 = 46/52
x/13 + 15/26 = 23/26
x/13 = 23/26 - 15/26
x/13 = 4/13
Có x/13 = 4/13
Suy ra : x = 4
Vậy x = 4
\(\frac{15}{26}+\frac{x}{16}=\frac{46}{52}\)
\(\frac{x}{16}=\frac{46}{52}-\frac{15}{26}\)
\(\frac{x}{16}=\frac{1}{4}\)
4 : 1 = 4
Suy ra x = 4

Nhầm, làm lại nhé!
\(\frac{x}{13}+\frac{15}{26}=\frac{46}{52}\)
\(\frac{x}{13}+\frac{15}{26}=\frac{23}{26}\)
\(\frac{x}{13}=\frac{23}{26}-\frac{15}{26}\)
\(\frac{x}{13}=\frac{23}{26}-\frac{15}{26}\)
\(\frac{x}{13}=\frac{4}{13}\)
\(\Rightarrow x=\frac{13.4}{13}=4\)
Vậy \(x=4\)
\(\frac{15}{16}+\frac{x}{13}=\frac{46}{52}\)
\(\Rightarrow\frac{x}{13}=\frac{46}{52}-\frac{15}{16}\)
\(\Rightarrow\frac{x}{13}=\frac{-11}{208}\)
\(\Rightarrow x=\frac{\left(-11\right).13}{208}\)
\(\Rightarrow x=\frac{-11}{16}\)
Vậy x = \(\frac{-11}{16}\)

\(\frac{x}{27}-\frac{2}{9}=\frac{6}{18}\)
\(\frac{x}{27}=\frac{6}{18}-\frac{2}{9}\)
\(\frac{x}{27}=\frac{3}{9}-\frac{2}{9}\)
\(\frac{x}{27}=\frac{1}{9}\)
\(\frac{x}{27}=\frac{3}{27}\)
\(x=3\)
Ấy nhầm, làm lại nha:
\(\frac{x}{27}-\frac{2}{9}=\frac{6}{18}\)
\(\frac{x}{27}=\frac{6}{18}+\frac{2}{9}\)
\(\frac{x}{27}=\frac{3}{9}+\frac{2}{9}\)
\(\frac{x}{27}=\frac{5}{9}\)
\(\frac{x}{27}=\frac{15}{27}\)
\(x=15\)
15/26 + x/16 = 46/52
x/16 = 46/52 - 15/26
x/16 = 1/4
x/16 = 4/16
Suy ra: x = 4
Vậy x = 4
\(\frac{15}{26}+\frac{x}{16}=\frac{46}{52}\)
\(\Rightarrow\frac{x}{16}=\frac{45}{52}-\frac{15}{26}\)
\(\Rightarrow\frac{x}{16}=\frac{4}{13}\Rightarrow\frac{64}{208}=\frac{x}{16}=\frac{64}{208}=\frac{x}{208}\Rightarrow x=64\)
\(\frac{46}{52}-\frac{15}{26}=\frac{46}{52}-\frac{30}{52}=\frac{16}{52}=\frac{4}{13}\)
\(\frac{15}{26}+\frac{x}{16}=\frac{46}{52}\)
\(\Leftrightarrow\frac{15}{26}+\frac{x}{16}=\frac{23}{26}\)
\(\Leftrightarrow\frac{x}{16}=\frac{23}{26}-\frac{15}{26}\)
\(\Leftrightarrow\frac{x}{16}=\frac{8}{26}=\frac{4}{13}\)
\(\Rightarrow13x=16\times4\)
\(\Rightarrow x=\frac{64}{13}\)
\(\frac{x}{13}:\frac{15}{16}=\frac{46}{52}\)
\(\Rightarrow\frac{x}{13}=\frac{46}{52}\cdot\frac{15}{16}=\frac{23}{26}\cdot\frac{15}{16}\)
\(\Rightarrow\frac{x}{13}=\frac{345}{416}\)
\(\Rightarrow x=\frac{345}{416}\cdot13=\frac{345}{32}\)
Vậy \(x=\frac{345}{32}\)

\(\frac{x}{13}:\frac{15}{16}=\frac{46}{52}\)
\(\Rightarrow\frac{x}{13}:\frac{15}{16}=\frac{23}{26}\)
\(\Rightarrow\frac{x}{13}=\frac{23}{26}\times\frac{15}{16}\)
\(\Rightarrow\frac{x}{13}=\frac{345}{416}\)
\(\Leftrightarrow416\times x=13\times345\)
\(\Rightarrow416\times x=4485\)
\(\Rightarrow x=4485:416\)
\(\Rightarrow x=\frac{345}{32}\)
