A video game costs $ 21 more than a controller. Together, the video game
and the controller cost $ 76. Determine the cost x of the controller
What is the cost of the game?

The cost of the video game (x) is $48.50 and the cost of the controller (y) is $27.50

Step-by-step explanation:

A video game (X) costs $21 more than a controller (y), this is (y+21=x). Together, the video game and the controller cost $76 (x+y=76). Determine the cost of x of the controller. What is the cost of the game?

We have to find x and y.

Our equations are:

We can replace x in the second equation by our respective value of x shown in the first equation.

Now replace to find x.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

a is the correct
