Plissssssssssss na jutro!!!!!!Pomocy!!
1.Zapisz w najprostszej postaci wyrażenia:
a) (2a+3)+(4a-1)= b) 8a-(3b-a)= c) 2-(4a-1)-3a= d) (7a-b)-(2b+a)= e)(4x-2y)+(3x-y)-(x+2y)= f) 8-x do potęgi 2+(-3x do pot.2 +4)= g) (p-2q)-(3p+4q)-p+2q= h)-(2x-4)+(4-2x)= i) 5a-(3a+1)= j)-2x-(3-5x)= k) -4y-(7y-3z+1)= l)6ab-(5a-4b+ab)= m)-3xy-(-2x+5y-3xy)= n) (4z-3)-(5x+2yz-4)+2yz= o) 4x+(-3x+2)-2x+1= p)3+(2x-1)+(4-x)= szybko błagam!:)" Life is not a problem to be solved but a reality to be experienced!

a) (2a+3)+(4a-1)= 2a+3+4a-1= 6a+2
b) 8a-(3b-a)=8a -3b+a= 9a-3b
c) 2-(4a-1)-3a= 2-4a+1-3a= -7a+3
d) (7a-b)-(2b+a)= 7a-b-2b-a= 6a-3b
e)(4x-2y)+(3x-y)-(x+2y)= 4x-2y + 3x-y-x-2y= 6x-5y
f) 8-x²+(-3x² +4)=8-x²-3x²+4=12-4x²
g) (p-2q)-(3p+4q)-p+2q= p-2q-3p-4q-p+2q= -3p-4q
h)-(2x-4)+(4-2x)=-2x+4+4-2x= -4x+8
i) 5a-(3a+1)=5a-3a-1= 2a-1
j)-2x-(3-5x)= -2x-3+5x= 3x-3
k) -4y-(7y-3z+1)= -4y-7y+3z-1 = -11y+3z-1
l)6ab-(5a-4b+ab)= 6ab-5a+4b-ab= 5ab-5a+4b
m)-3xy-(-2x+5y-3xy)= -3xy+2x-5y+3xy=2x-5y
n) (4z-3)-(5x+2yz-4)+2yz= 4z-3-5x-2yz+4+2yz= 4z+1-5x
o) 4x+(-3x+2)-2x+1=4x-3x+2-2x+1 = -x+3
p)3+(2x-1)+(4-x)=3+2x-1+4-x= 6+x
