Question

32,5 x X + 5,5 x X + X = 3

Answer 1

\(32,5\times X+5,5\times X+X=3\)

\(X\times\left(32,5+5,5+1\right)=3\)

\(X\times\left(38+1\right)=3\)

\(X\times39=3\)

\(X=3:39\)

\(X=\dfrac{1}{13}\)

Answer 2

\(32,5\times x+5,5\times x+x=3\)

\(x\times\left(32,5+5,5+1\right)=3\)

\(x\times39=3\)

\(x=3:39\)

\(x=\dfrac{1}{13}\)

Đáp số: \(x=\dfrac{1}{13}\)
