Question

4,75 - x = 2/5 -3/5            x - 4/7= 5/3

Answer 1

4,75 - \(x\) = \(\dfrac{2}{5}\) - \(\dfrac{3}{5}\)

4,75 - \(x\) = \(\dfrac{-1}{5}\)

            \(x\) = 4,75 + 0,2

              \(x\) = 4,95

\(x\) - \(\dfrac{4}{7}\) = \(\dfrac{5}{3}\)

\(x\)        = \(\dfrac{5}{3}\) + \(\dfrac{4}{7}\)

\(x\)        = \(\dfrac{47}{21}\)

Answer 3

\(4,75-x=\dfrac{2}{5}-\dfrac{3}{5}\)

\(\Rightarrow\dfrac{475}{100}-x=-\dfrac{1}{5}\)

\(\Rightarrow\dfrac{19}{4}-x=-\dfrac{1}{5}\)

\(\Rightarrow x=\dfrac{19}{4}+\dfrac{1}{5}=\dfrac{95}{20}+\dfrac{4}{20}=\dfrac{99}{20}\)

\(x-\dfrac{4}{7}=\dfrac{5}{3}\Rightarrow x=\dfrac{5}{3}+\dfrac{4}{7}=\dfrac{35}{21}+\dfrac{12}{21}=\dfrac{47}{21}\)

Answer 4

4,75 - $x$ = 2552​ - 3553​

4,75 - $x$ = −155−1​

            $x$ = 4,75 + 0,2

              $x$ = 4,95

$x$ - 4774​ = 5335​

$x$        = 5335​ + 4774​

$x$        = 47212147​

Answer 5

4,75 - $x$ = 2552​ - 3553​

4,75 - $x$ = −155−1​

            $x$ = 4,75 + 0,2

              $x$ = 4,95

$x$ - 4774​ = 5335​

$x$        = 5335​ + 4774​

$x$        = 47212147​
