Is the expression 2f + 4f + 2 – 3 equivalent to 6f – 1?

6f – 1 evaluated at f = 9 is 53.

2f + 4f + 2 – 3 evaluated at f = 9 is also 53.

6f – 1 evaluated at f = 3 is 17.

what is 2f + 4f + 2 – 3 evaluated at f = 3?

iv been stuck for 10 min now

Yes it is equivalent.

Step-by-step explanation:

In this case the only thing that you have to do to know if the two expressions are equivalent are put them on opposite sides of the equation like this:

6f-1= 2f+4f+2-3

When you simplify this you´ll end up with the next equation:

6f-1= 6f -1

In this case you can see that both expressions are equivalent because they are the same once you put them on opposite sides of the equation.

what is the original number? you forgot to add it.
