Question

Решите уравнение: 3х+4 3/5=6 1/9

Answer 1

3х= 6 1/9 - 4 3/5 = 6 5/45 - 4 27/45 = 5 50/45 - 4 27/45 = 1 23/45 
1 23/45 /3 = 68/45  /  3 = 68/135

Answer 2

А чему х равен?

Answer 3

$3x+4 frac{3}{5} =6 frac{1}{9} \ 3x+ frac{4*5+3}{5}= frac{6*9+1}{9}\ 3x+ frac{23}{5}= frac{55}{9} \ 3x= frac{55*5-23*9}{45}= frac{275-207}{45}= frac{68}{45}\ x= frac{68}{135}$
