Question

Giải phương trình: \(\frac{7x-1}{6}+2x=\frac{16-x}{5}\)

Answer 1

........

<=>\(\frac{5\left(7x-1\right)}{5.6}+\frac{2x.30}{1.30}=\frac{6\left(16-x\right)}{6.5}\)

<=>\(35x-5+60x=96-6x\)

<=>\(35x+60x+6x=96+5\)

<=>\(101x=101\)

<=>\(x=1\)

Answer 2

\(\frac{7x-1}{6}+2x=\frac{16-x}{5}\)

\(\frac{35x-5}{30}+\frac{60x}{30}-\frac{96-6x}{30}=0\)

\(\frac{35x+60x+6x-5-96}{30}=0\)

\(\frac{95x-101}{30}=0\)

\(95x-101=0\)

\(95x=101\)

\(x=\frac{101}{95}\)
