Question

100 * (x - 1) + 5 = 5 - \(\frac{1}{\frac{1}{2}}\)

Answer 1

\(100\cdot\left(x-1\right)+5=5-2\)

\(100\cdot\left(x-1\right)+5=3\)

\(100\cdot\left(x-1\right)=3-5=-2\)

\(x-1=-2:100=-\frac{1}{50}\)

\(x=-\frac{1}{50}+1\)

\(x=\frac{49}{50}\)

Answer 2

100 * (x - 1) + 5 = 5 - \(\frac{1}{\frac{1}{2}}\)

\(\Rightarrow100x-100+5=5-2\)

\(\Rightarrow100x-100+5=3\)

\(\Rightarrow100x-100=-2\)

\(\Rightarrow100x=98\)

\(\Rightarrow x=\frac{49}{50}\)
