Ta có :
x/36 = -2/3 + 5/12
x/36 = -1/4
x = -1/4 x 36
x = -9
Hok tốt !
\(\frac{x}{36}\)=\(\frac{-2}{3}\)+\(\frac{5}{12}\)
\(\frac{x}{36}\)=\(\frac{-1}{4}\)
x.4=36.1
4x=36
x=9
x.4=36.-1
4x=-36
x=-9
lúc nãy là lỗi kĩ thuật
\(\frac{x}{36}=\frac{2}{3}+\frac{5}{12}\)
\(\frac{x}{36}=\frac{24}{36}+\frac{15}{36}\)
\(\frac{x}{36}=\frac{39}{36}\)
\(\Rightarrow x=39\)
vậy:\(x=39\)
k mk bạn nha^-^
