Question

2,4x +1,2=8,9-7,2
решите

Answer 1

2,4x = 1,2-8,9+7,2 2,4x=0 x =0

Answer 2

2,4x+1,2=8,9-7,2
2,4x=8,9-7,2-1,2
2,4x=0,5

$x= \frac{0,5}{2,4} = \frac{5}{10} : 2 \frac{4}{10} = \frac{5}{10} : \frac{24}{10} = \frac{5}{10} * \frac{10}{24} = \frac{5}{1} * \frac{1}{24} = \frac{5}{24}$

$x= \frac{5}{24}$
