X/500-x/700=2 решите уравнение

Question

X/500-x/700=2 решите уравнение

Answer 1

Х/500 - х/700 = 2
7х/3500 - 5х/3500 = 2
2х/3500 = 2
2х = 2 * 3500
2х = 7000
х = 7000/2
х = 3500
3500/500 - 3500/700 = 2
24500/3500 - 17500/3500 = 2
7000/3500 = 2
2 = 2

Answer 2

7х/3500-5х/3500=2
2х/3500=2
2х=7000
х=3500
