Question

\(\frac{37-x}{3}=\frac{x-13}{7}\)

Answer 1

\(\frac{37-x}{3}=\frac{x-13}{7}\)

\(\Rightarrow7\left(37-x\right)=3\left(x-13\right)\)

\(\Leftrightarrow259-7x=3x-39\)

\(\Leftrightarrow259+39=3x+7x\)

\(\Leftrightarrow298=10x\)

\(\Leftrightarrow x=29.8\)

Answer 2

\(\frac{37-x}{3}=\frac{x-13}{7}\)

\(\Rightarrow7\left(37-x\right)=3\left(x-13\right)\)

\(\Rightarrow259-7x=3x-39\)

\(\Rightarrow259+39=3x+7x\)

\(\Rightarrow298=10x\)

\(\Rightarrow x=\frac{298}{10}=\frac{149}{5}\)

Answer 3

       7(37-x) = 3(x-13)

<=> 259 - 7x = 3x -39

<=> 10x = 298

<=> x=\(\frac{298}{10}\)

<=> x = \(\frac{149}{5}\)

Answer 4

\(\frac{37-x}{3}=\frac{x-13}{7}\)

\(\Leftrightarrow\left(37-x\right).7=\left(x-13\right).3\)

\(\Rightarrow259-7x=3x-39\)

\(10x=298\Rightarrow x=29.8\)
