What is the value of f? 6f−12=−4f+6

Xelga [282]

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

$6f-12+12=-4f+6+12$

Then simplify.

$6f=-4f+18$

Next, add by four-f from both sides of equation form.

$6f+4f=-4f+18+4f$

Simplify.

$10f=18$

Then you divide by ten from both sides of equation form.

$\frac{10f}{10}= \frac{18}{10}$

Finally simplify by equation.

$f=\frac{9}{5}$

Final answer: $\boxed{f=9/5}$

Hope this helps!

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