4(4a-7b)-7(3a-5b)-2(6b-5a)= ?



0,5(8x-12y)+0,6(5x-15y)= ?

Answer 1

4(4a-7b)-7(3a-5b)-2(6b-5a)= 16a-28b-21a+35b-12b+10a=5a-5b
0,5(8x-12y)+0,6(5x-15y)=4x-6y+3x-9y=7x-15y

Answer 2

4(4a-7b)-7(3a-5b)-2(6b-5a)=16a-28b-21a+35b-12b+10a=5a-5b

0,5(8x-12y)+0,6(5x-15y)=4x-6y+3x-9y=7x-15y

Answer 3

4(4a-7b)-7(3a-5b)-2(6b-5a)=16a-28b-21a+35b-12b+10a=5a-5b





0,5(8x-12y)+0,6(5x-15y)=4x-6y+3x-9y=7x-15y
