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