Solve for f: 6f + 9g = 3g + f
andrezito [222]

Answer:

f= -(6/5)g

Explanation:

We have been given the expression 6f+9g = 3g+f

Solve for f means find the value of f

We will simplify the given expression:

we will collect the values of f at one side  and g on the other side

So, rewriting the given expression  6f+9g =3g+f  as 6f-f=3g-9g

So, after simplification it will lead to  5f= -6g

After further simplification f= -(6/5)g which is the final result
