Question

Решите уравнение))) 34*х -12 =260 ,
2400:(317+х)=3

Answer 1

34х - 12 = 260
34х = 260 +12 = 272
х = 272/34 = 8

2400:(317+х)=3
2400 = 3*(317+х) = 951+3х
3х = 2400-951 =1449
х = 1449/3 = 483

Answer 2

34x-12=260
34x=260+12
34x=272
x=272/34
х=8
Ответ: 8
2400:(317+х)=3
317+х=2400:3
317+х=800
х=800-317
х=483
Ответ: 483
