Sa se calculeze inecuatia: x+2/5 + 3/2 = 1/10 + x-3/20

Răspuns :

x+2/5 + 3/2 = 1/10 + x-3/20 prima=x amplificam cu 4
a 2 a cu 10
a 3a cu 2
a 4 a ramane asa,deci
4x+8+30=2+x-3/ inmultim cu 20 ca sa scapam de numitor
4x+38=x-1
4x-x= -1+38
3x=37
x=37/3
[tex]x+ \frac{2}{5}+ \frac{3}{2}= \frac{1}{10}+x- \frac{3}{20}\\ x+ \frac{19}{10}=x-\frac{1}{20} \\ x-x=-\frac{1}{20}-\frac{19}{10} \\ 0x=-\frac{39}{20} [/tex]
