Question

\(\text{tìm x}:\)

\(\text{3-4x+24+6x=x+27+3x}\)

Answer 1

\(3-4x+24+6x=x+27+3x\)

\(2x+27=4x+27\)

\(2x=4x\)

\(x=2x\)

\(x=0\)

Answer 2

3 - 4x + 24 + 6x = x + 27 + 3x

=> -x - 4x + 6x - 3x = - 3 - 24 + 27

=> x( - 1 - 4 + 6 - 3) = 0

=> x. (- 2)                 = 0

=> x                          = 0 : (-2)

=> x                          = 0

Answer 3

\(3-4x+24+6x=x+27+3x\)

\(\Leftrightarrow3+24-4x+6x=27+x+3x\)

\(\Leftrightarrow27+2x=27+4x\)

\(\Leftrightarrow27-27=-2x+4x\)

\(\Leftrightarrow2x=0\)

\(\Rightarrow x=0\)
