Question

rac{f}{2} = - 1" alt=" - 7 + \frac{f}{2} = - 1" align="absmiddle" class="latex-formula">

Answer 1

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!
