Answer:
b=2
Explanation:
We fist of all open the brackets.
6(2b-4) =0
= 12b-24=0
Then we combine like terms
( whenever a sign crosses over an equal to sign it changes)
12b = 0+24
12b=24
Divide by co-efficient of b which is 12
12b = 24
12 12
Divide both sides by 6.
(Anything divide by zero will give you zero, and anything plus zero gives itself)
Add 4 to both sides.
Divide both sides by 2.
