Odpowiedź :
a) 3b+(b+1)= 3b + b + 1 = 4b + 1
B) 8n-3+(-5n+7)= 8n - 3 - 5n + 7 = 3n + 4
C) 5a-(a+1)= 5a - a - 1 = 4a - 1
D) 6x-(3+5x)= 6x - 3 - 5x = x - 3
E) 8-3y-(-7-y+5)= 8 - 3y + 2 + y= 10 - 2y
F) 3+(8u-5)-(5u+2)= 3 + 8u - 5 - 5u - 2 = -4 + 3u
G)7z-(3-4z)+(5+z)= 7z - 3 + 4z + 5 + z = 12z + 2
H)1-5w-(w+3)-(4w-6)= 1 - 5w - w - 3 - 4w + 6 = 4 - 10w
Odpowiedź:
a) 3b+(b+1)=3b+b+1=4b+1
b) 8n-3+(-5n+7)=8n-3-5n+7=3n+4
c) 5a-(a+1)=5a-a-1=4a-1
d) 6x-(3+5x)=6x-3-5x=x-3
e) 8-3y-(-7-y+5)=8-3y+7+y-5=-u+10
f) 3+(8u-5)-(5u+2)=3+8u-5-5u-2=3u-4
g) 7z-(3-4z)+(5+z)=7z-3+4z+5+z=12z+2
h) 1-5w-(ww+3)-(4w-6)=1-5w-w-3-4w+6=-10w+4
