5-×/5 - 2-×/6 = 7/10 di jawab yh menggunakan cara

[tex] \frac{5 - x}{5} - \frac{2 - x}{6} = \frac{7}{10} [/tex]
kalikan kedua ruas dengan 30

6 (5-x)-5 (2-x)=21
30-6x-10+5x=21
20-x=21
-x=-20+21
-x=1
x=-1

semoga membantu

5-x / 5 - 2-x / 6 = 7 / 10
30-6x / 30 - 10-5x / 30 = 7 / 10
30 . 30-6x / 30 - 10-5x / 30 = 30 . 7 / 10
30 - 6x - 10 - 5x = 21
20 - 11x = 21
11x = 21 -20
11x = 1
x = 1 ÷ 11
x = 0,090909090909090909....
