What is the value of g? −5+7g=3g+9 , i need this answer asap, .

The value of g would be 3.5. 

I got this by simplifying like terms, which in this case you can start by adding five to both sides to get -

7g = 3g +14

You can then subtract 3g from both sides -

4g = 14

and finally you just divide both sides by 4 to get g by itself. This leaves you with -

g = 3.5
