Tìm X

X : 8 x 32 + X : 3 x 18 - X : 5 x 10 = 120

Answer 1

X : 8 x 32 + X : 3 x 18 - X : 5 x 10 = 120 

X : (32 :8 ) + X : ( 18 :3 ) - X : ( 10 : 5 )

X = ( 4 +6 -2 )=120

X= 8  = 120

X=120 :8 

X = 15 

Answer 2

\(x\div8\times32+x\div3\times18-x\div5\times10=120\)

\(x\div\left(8\div32\right)+x\div\left(3\div18\right)-x\div\left(5\div10\right)=120\)

\(x\div\frac{1}{4}+x\div\frac{1}{6}-x\div\frac{1}{2}=120\)

\(x\div\left(\frac{1}{4}+\frac{1}{6}-\frac{1}{2}\right)=120\)

\(x\div\frac{-1}{12}=120\)

\(x=120\times\frac{-1}{12}\)

\(x=-10\)
