F(x)=2x+7
X=?

Need answers ASAP

x = -

Step-by-step explanation:

The first step would be to sybstitute  F (x) with 0

0 = 2x + 7

Then the variable can be put on the left to replace 0

-2x = 7

When you divide both sides you get

x = - or x= -3.5

Depends on what you need for your anser ( a decimal or fraction )

Hope this helps!
