Question

4 ( 2a+ b ) - 6 ( 2a+b )​

Answer 1

8a+4b-12a-6b=0

-4a-2b=0

-4a=2b

a=-1/2 b

or

b=-2a

Answer 2

Answer:

4 (2a-b)-6 (2a-b)

= 8a - 4b -12a + 6b

= -4a +2b =0 ----1.

2b = 4a

4a/ 2 = b-----2.

put in 1.

-4a + 2(4a/2) = b

-4a + 4a = b

hence b = 0

put it 1

-4a + 2(0) = 0

-4a =0

a= 0
