Solve these equation<br><br>4(3-x)=(1-2x)​
serg [7]

To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.

:\implies\tt{4(3 - x) = (1 - 2x)}

:\implies\tt{(12 - 4x) = (1 - 2x)}

:\implies\tt{12 - 4x = 1 - 2x}

Combining like terms, we get,

:\implies\tt{12 - 1 =  - 2x + 4x}

:\implies\tt{11 = 2x}

:\implies\tt{2x = 11}

:\implies\tt{x =  \frac{11}{2} }

:\implies\tt{x = 5.5}

  • The value of x is 5.5
