What is 5+6f =11 hhhhhhhhhhyhy

zepelin [54]

Hello!

Answer:

$\boxed{f=1}$

The answer should have positive sign.

Step-by-step explanation:

First, you subtract by 5 from both sides of an equation.

$5+6f-5=11-5$

Then, simplify and subtract by the numbers from left to right.

$11-5=6$

$6f=6$

You divide by 6 from both sides of an equation.

$\frac{6f}{6}=\frac{6}{6}$

Finally, divide numbers from left to right.

$6\div 6=1$

$\boxed{f=1}$ , which is our correct answer.

Hope this helps you!

Have a nice day! :)
