a) 3b+(b+1)=3b+b+1=4b+1
b) 5a-(a+1)=5a-a-1=4a-1
c) 2x-(3-5-x)=2x-(-2-x)=2x+2+x=3x+2
d) 2a+(3a-2b)+(a+b)=2a+3a-2b+a+b=6a-b
e) 5a-(2-x)+b-2x+5=5a-2+x+b-2x+5=5a+b-x+3
f) 7k-(m-2n+k)-(5k-3)+(2k-1)=7k-m+2n-k-5k+3+2k-1=3k-m+2n+2
g)0,3x-(5+0,7y)-(0.9-0.1x)+(x-0,1)=0,3x-5-0,7y-0,9+0,1x+x-0,1=1,4x-0,7y-6
h) 0,5a+(5-0,8b+2a)-(-b+1)=0,5a+5-0,8b+2a+b-1=2,5a+1,2b+4
a) 3b+(b+1)=3b+b+1=4b+1
b)5a-(a+1)=5a-a-1=4a-1
c)2x-(3-5-x)=2x-(-2-x)=2x+2+x=3x+2
d)2a+(3a-2b)+(a+b)=2a+3a-2b+a+b=6a-b
e)5a-(2-x)+b-2x+5=5a-2+x+b-2x+5= 5a+3+b-x
f)7k-(m-2n+k)-(5k-3)+(2k-1)= 7k-m+2n-k-5k+3+2k-1=3k-m+2+2n
g)0.3x-(5+0,7y)-(0.9-0.1)+(x-0.1)=0.3x-5-0,7y-0,9+0,1+x-0,1=1,3x-0,7y-5
h)0,5a+(5-0,8b+2a)-(-b+1)= 0,5a +5-0,8b+2a+b-1=2,5a+4+0,2b
