Step-by-step explanation:
Let x = number of games that Alex played
The total money that he spent C is given by
If he spent $45, then we can write
![45 = 2x + 15](https://tex.z-dn.net/?f=45%20%3D%202x%20%2B%2015)
Solving for x, we get
![2x = 45 - 15 = 30 \Rightarrow x = 15](https://tex.z-dn.net/?f=2x%20%3D%2045%20-%2015%20%3D%2030%20%5CRightarrow%20x%20%3D%2015)
This means that Alex played 15 games.
Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
