$- x - 3 - x - 4 = 1 \\ - 2x = 1 + 3 + 4 \\ - 2x =8 \\ x = - 4$

$8.3 - 2x = 0.5 \\ - 2x = 0.5 - 8.3 \\ - 2x = - 7.8 \\ x = 3.9$

$\frac{1}{2} - x + \frac{1}{2} x = 2 \frac{1}{2} \\ - \frac{1}{2} x = 2 \\ x = - 4$

$\frac{1}{2} x + \frac{1}{5} x - \frac{1}{10} x = 2 \\ 0.5x + 0.2x - 0.1x = 2 \\ 0.6x = 2 \\ \frac{6}{10}x = 2 \\ 6x = 20 \\ x = 3 \frac{1}{3}$

Odpowiedź:

i) x= -4

j) x= 3,9

k) x= -4

l) x= 3 i 2/6

Szczegółowe wyjaśnienie:

i)-x-3-x-4=1

-2x-7=1

-2x=8

x=-4

j)83/10-2x=5/10

-2x=-78/10

2x=7,8

x=3,9

k)5/10-x+5/10x=2 i 5/10

-5/10x=2

x=-4

l)5/10x+2/10x-1/10x=2

6/10x=2 | *10

6x=20

x=3 i 2/6
