Question

Решите дробные уравнения с решением
5x=7
0.5x=2
2:x=5
4x=1
0.4x=3
3:x=5

Answer 1

Ответ:

$5x = 7 \\ x = 7 \div 5 \\ x = 1.4$

$0.5x = 2 \\ x = 2 \div 0.5 \\ x = 4$

$2 \div x = 5 \\ 5x = 2 \\ x = 2 \div 5 \\ x = 0.4$

$4x = 1 \\ x = 1 \div 4 \\ x = 0.25$

$0.4x = 3 \\ x = 3 \div 0.4 \\ x = 7.5$

$3 \div x = 5 \\ 5x = 3 \\ x = 3 \div 5 \\ x = 0.6$
