The second to last statement: he needed to divide both sides of the equation by 5
Since we want to isolate a, which is multiplied to 5, we want to do the opposite which is divide by 5.
Answer:
$244
Step-by-step explanation:
f(x) = 60x + 4 and g(x) = 2x-4
We are told to find f(g=4), when Mike makes four tables.
We have to put replace x in f(x) with the value g(x) when x is 4, like this:
f(x) = 60x + 4 // Replace x with g(x) = 2x-4
f(x) = 60(2x-4) + 4
f(x) = (120x - 240) + 4 // Solve
f(x) = (120*4 - 240) +4 // They tell us x=4
f(x) = 480 - 240 + 4 = $244
Okay, so first you are going to decide whether to solve for x or solve for y. I am going to solve for x. In order to do so, you must get x by itself.

![2x=y-6[ [tex]3x-4y=-4](https://tex.z-dn.net/?f=2x%3Dy-6%5B%20%5Btex%5D3x-4y%3D-4)

The next step is to set both equations equal to each other in order to find y.
\frac{y-

6}{2} [/tex]
So now you know that y=-2. The next part is substitution. All you have to do is pick on of the equations and plug in the y value to get the x value.
So your answer to the question is (-4,-2). I hope I've helped you understand how to solve these types of problems. If you have any questions, don't hesitate to ask.
