Question

Giải PT sau:

\(2,3x-2.\left(0.7+2x\right)=36-4,7x\)

Answer 1

\(\Leftrightarrow2,3x-1,4-4x=36-4,7x\Leftrightarrow3x=37,4\Leftrightarrow x=\dfrac{37,4}{3}\)

Answer 2

\(2,3x-2\left(0,7+2x\right)=36-4,7x\\ \Leftrightarrow2,3x-1,4-4x-36+4,7x=0\)

\(\Leftrightarrow3x-37,4=0\\ \Leftrightarrow x=\dfrac{187}{15}\)

Answer 3

=>2,3x-1,4-4x=36-4,7x

=>x=37,4/3
