a -7+3y+9+2y=2+5y
b X -3X+2-2X-7=-7-5
c -5X+4y-y-7x-9y=-12x-6y
d 4x+5-x-4+x-3x=x+1
e 0,5a-2a+9-0,5a-11,5= -2a-2,5
f -14k+9k-13+k+3+4k=-10 ponieważ k się wszystkie zredukują
g -3k+2m+5m-7+k-m= -2k+6m-7
h 2x-4+3x=5x-4
i x-3y-2x+6y=-x-3y
j 2y-5-3y-4-8y+9=-9y
a
-7+3y+9+2y=
= 3y + 2y - 7 + 9=
= 5y + 2
b
x -3x+2-2x-7=
= x - 3x - 2x +2 - 7=
= - 4x - 5
c
-5x+4y-y-7x-9y=
= -5x - 7x + 4y - y - 9y=
= - 12x - 6y
d
4x+5-x-4+x-3x=
= 4x - x + x - 3x + 5 - 4=
= x + 1
e
0,5a-2a+9-0,5a-11,5=
= 0,5a - 2a - 0,5a + 9 - 11,5=
= -2a - 2,5
f
-14k+9k-13+k+3+4k=
= - 14k + 9k + k + 4k - 13 + 3=
= - 10
g
-3k+2m+5m-7+k-m =
= - 3k + k + 2m + 5m - m - 7=
= -2k +6m - 7
h
2x-4+3x=
= 2x + 3x - 4=
= 5x - 4
i
x-3y-2x+6y=
= x - 2x - 3y + 6y =
= - x + 3y
j
2y-5-3y-4-8y+9=
= 2y - 3y - 8y - 5 - 4 +9 =
= - 9y
