Question

(0.5x - 3/7 ) :  1/2 =\(1\dfrac{1}{7}\)

Answer 1

\(\Leftrightarrow\dfrac{1}{2}x-\dfrac{3}{7}=\dfrac{8}{7}\cdot\dfrac{1}{2}=\dfrac{4}{7}\\ \Leftrightarrow\dfrac{1}{2}x=1\Leftrightarrow x=2\)

Answer 2

(0,5 . x - 3/7) : 1/2 = 1_1/7

(0,5 . x - 3/7) : 1/2 = 8/7

(0,5 . x - 3/7) = 8/7 . 1/2

(0,5 . x - 3/7) = 4/7

0,5 . x = 4/7 + 3/7

0,5 . x = 1

x = 1 : 0,5

x = 2
