Answer:

0 or 6

Step-by-step explanation:

2aa = 12a

2a² = 12a

Subtract 12a from both sides.

2a² - 12a = 0

Factor left side of equation.

2a(a - 6)=0

Set factors equal to 0.

2a = 0

a =

a - 6 = 0

a = 6

Answer: A = 6
Explanation:
2A x A = 12A
2A=12A/A
2A=12
A=12/2=6

Now let’s take A = 6 and try it in the equation

2(6) x 6=12(6)
12 x 6= 12 x 6
72= 72

So A = 6 is the right answer
