Odpowiedź :

-7+4y+9+3y =   2 + 7y

4x-4+3x-2 = 7x - 6

[tex]3\frac{1}{4} - x + 2\frac{1}{5}x - 2 = \frac{13}{4} - x + \frac{11}{5}x - 2 = \frac{13}{4} - \frac{6}{5}x - 2 = \frac{5}{4} + \frac{6}{5}x[/tex]

20x-5+4x-47 = 24x - 52

[tex]x - 3x + 2 - 0,2x - \frac{1}{7} = -2,2x + 1\frac{6}{7}[/tex]

[tex]\frac{2}{5}x + 2 + \frac{3}{5}x = x + 2[/tex]

3a-6a+8-5 = -3a + 3

x+7-4x+2 = -3 + 9

7x-6-4x+3 = 3x - 3

0,2x-0,6x+x-4 = 0,6x - 4

0,25-w-4+2 = -1,75 - w

2,5y+y-0,2y+10-2 = 3,3y + 8

[tex]\frac{3}{7}y - y + 4 = -\frac{4}{7}y + 4[/tex]

[tex]2\frac{3}{5} - 3a - 7 + 4 = \frac{13}{5} - 3a - 3 = -\frac{2}{5} - 3a[/tex]

-0,1z-2,5z-4+2-1 = -2,6z - 3
