x=1/2
c) -2x=-16 /:(-2)
x=8
28 - 4x + 10 - 6x = 8
38 - 10x = 8 | + 10x
38 = 8 + 10x | -8
30 = 10x | :10
3 = x
b)1/4x=2 | × 4
x = 8
c)-2x=-16 | +16
- 2x + 16 = 0 | +2x
16 = 2x | :2
8 = x
d)x-2 1/2=-3 |+ 2 1/2
x = - 1/2
mam nadzieję że pomogłam;)
28-4x+10-6x=8
-10x+38=8 /-38
-10x=-30 /(-10)
x=3
b) 1/4x=2 / 1/4
x=8
c) -2x=-16 / (-2)
x=8
d) x-2 1/2=-3 /+2 1/2
x= -1/2
