Question

\(\dfrac{2}{3}x+25\%x=1\)

Answer 1

\(< =>\dfrac{2}{3}x+\dfrac{1}{4}x=1\)

\(< =>\dfrac{11}{12}x=1\)

\(< =>x=\dfrac{12}{11}\)

Answer 2

2/3x+1/4x = 1

( 2/3 + 1/4)x = 1

 11/12x = 1

          x = 1 : 11/12

          x = 12/11

Answer 3

\(\dfrac{2}{3}x+25\%x=1\)

\(\Leftrightarrow x\cdot\dfrac{2}{3}+x\cdot\dfrac{1}{4}=1\)

\(\Leftrightarrow x\cdot\dfrac{11}{12}=1\)

hay \(x=\dfrac{12}{11}\)
