Question

100 - ( 1 - x ) + 99 ( x - 1 ) = 1

3 ( 2 - x ) + 5 ( x - 6 ) = -98

Answer 1

\(100-\left(1-x\right)+99\left(x-1\right)=1\)

\(100+\left(x-1\right)+99\left(x-1\right)=1\)

\(100+\left(x-1\right)\left(1+99\right)=1\)

\(100\left(1+x-1\right)=1\)

\(100x=1\)

\(x=\frac{1}{100}\)

Answer 2

a,  =>   100 + ( x - 1 ) + 99 ( x - 1 ) = 1

     => 100 +  ( x - 1 ) .100 = 1 

     =>  100 . x = 1 

    =>   x = \(\frac{1}{100}\)    

b,   =>  6 -3x + 5x - 60 = -98 

      =>   2x - 54 = -98 

      =>   2x = -44 

     =>   x = -22
