Question

1) 3,3a+(a-4)=

2) 5a- (0,7a+8)=

3) 5,3b-(2b+3)=

4) 9,6b+7-0,4b=

Answer 1

1) 3,3a+(a-4)=3,3а+а-4=4,3а-4
2) 5a- (0,7a+8)=5а-0,7а-8=4,3а-8
3) 5,3b-(2b+3)=5,3b-2b-3=3.3b-3
4) 9,6b+7-0,4b=9.2b+7

Answer 2

1) 3,3a+(a-4)=4.3a-4

2) 5a- (0,7a+8)=4.3a-8

3) 5,3b-(2b+3)=3.3b-3

4) 9,6b+7-0,4b=9.2b+7
