Answer:

f=6

Explanation:

it's asking what 2 times f = 12. You just have to figure out what times 2 equals 12. To check your work, just replace the variables (f) with the solution (6) to see if you were right.

Answer:

#f=6#

Explanation:

#2*f=12#

#(2*f)/2 = 12/2#

#f = 12/2#

#f = 6#

Answer:

The answer is #f=6#.

Explanation:

When you're dealing with one-variable equations, you can perform the actions to get the variable on one side of the equation, as long as you perform those actions on both sides of the equations. Here's our problem:

#2f=12#

Now, we can divide both sides by #2#:

#2fcolor(red)(/2)=12color(red)(/2)#

The #2#'s on the left side of the equation cancel out because #2color(black)/2 = 1#.

#cancel(2)fcolor(red)/cancel(color(red)2) = 12color(black) / 2#

#f = 12color(black)/2#

Since #12color(black)/2 = 6#,

#f=6#

You can check if this answer is correct by plugging it back into the original problem:

#2f=12#

#=>2*6=12#

#12 = 12#

Since this is true, the answer is correct.
