Question

If 6(2b-4) = 0, then b=?

Answer 1

Answer:

b=2

Step-by-step 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

b=2

Answer 2

Answer:

• $\sf b=2$

Step-by-step explanation:

$\sf 6(2b-4)=0$

Divide both sides by 6.

(Anything divide by zero will give you zero, and anything plus zero gives itself)

$\sf 2b - 4=0$

Add 4 to both sides.

$\sf 2b = 4$

Divide both sides by 2.

$\sf \cfrac{2b}{2}=\cfrac{4}{2}$

$\sf b = 2$
