Checking my answer for Let f(x) = 7x - 6 and g(x) = 3x + 4. Find f(x) + g(x).? would it be just 10x-2 or is it possible to simplify more?

Checking my answer for Let f(x) = 7x - 6 and g(x) = 3x + 4.  Find f(x) + g(x).? would it be just 10x-2 or is it possible to simplify more?

I guess there's nothing more

anonymous · Answer

Is it possible to simplify to 1/5

asnaseer · Answer

you could factor out a 2 as 2 divides into both 10x and 2

What do you mean, @Lovely95 ? Is that the answer given to you?

parthkohli · Answer

Ahh yes we have the factorisation if needed.

unklerhaukus · Answer

$f(x) = 7x - 6$    and    $g(x) = 3x + 4$.

$$f(x) + g(x)=7x-6+3x+4$$$$\quad\qquad\qquad=10x-2$$$$\qquad\qquad\quad=2(5x-1)$$
i dont think you can go any further

anonymous · Answer

ok...thanks!

anonymous · Answer

I shouldnt be solving for x?

unklerhaukus · Answer

is that what the question is asking?
if so, go from here there is only two steps
f(x)+g(x)=10x−2

anonymous · Answer

...1/5?

parthkohli · Answer

This is a function, so you should really check if we have an equation or not. Here, no because it just tells to simplify.

anonymous · Answer

ok, im assuming you have to solve for x but it really doesnt say, thanks... :D

unklerhaukus · Answer

if the question is exactly what you wrote i dont think you have to solve for x

inkyvoyd · Answer

Lovely, you can't solve for x, because the equation is given in two variables (x and f(x) ). You would need a value of f(x) to solve for x.

unklerhaukus · Answer

$$x=\frac{f(x)+g(x)+2}{10}$$
