First you had to add by seven from both sides of equation form.

-7+\frac{f}{2}+7=-1+7

Then simplify by equation.

\frac{f}{2}=6

Next, you multiply by two from both sides of equation form.

\frac{2f}{2}=6*2

And finally, simplify by equation.

6*2=12

2*6=12

12/6=2

12/2=6

f=12

Final answer: \boxed{f=12}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

lubasha [3.4K]

Answer:

11+3x=68

x=19

Step-by-step explanation:

11+3x=68 is your equation.

subtract 11 from both side to get 3x alone

3x=68-11

3x=57

divide 3 from both sides to get x alone

x=57/3

x=19

19 is your number.

<em><u>Answer:</u></em>

True

<em><u>Step-by-step explanation:</u></em>

So, again, from the most right column, we can add 5, -6, and -2 to get -3. We now know that every row or column must be equal to -3.

The question is asking if the number square below is -3. We found out from above that is -3 so it's true.
