Question

реши уравнение 1 7/8-2х=5/8​

Answer 1

$1 dfrac{7}{8} - 2x = dfrac{5}{8} \\ 2x = 1 dfrac{7}{8} - dfrac{5}{8} \\ 2x = 1 dfrac{2}{8} \\ x = 1 dfrac{2}{8}div 2 \\ x = dfrac{10}{8}cdot dfrac{1}{2} \\ x = dfrac{10}{16} \\ x = dfrac{5}{8}$

----------------------

$1 dfrac{7}{8} - 2cdot dfrac{5}{8} = dfrac{5}{8} \\ {} ;;;;;;;;;;;;; dfrac{5}{8} = dfrac{5}{8}$
