![y = 2x \\ y = 7x + 15](https://tex.z-dn.net/?f=y%20%3D%202x%20%5C%5C%20y%20%3D%207x%20%2B%2015)
Substitute the given value of y into the equation y=7x+15
![2x = 7x + 15](https://tex.z-dn.net/?f=2x%20%3D%207x%20%2B%2015)
Move the variable to the left-hand side and change its sign
![2x - 7x = 15](https://tex.z-dn.net/?f=2x%20-%207x%20%3D%2015)
Collect like terms
![- 5x = 15](https://tex.z-dn.net/?f=%20-%205x%20%3D%2015)
Divide both sides of the equation by -5
![x = - 3](https://tex.z-dn.net/?f=x%20%3D%20%20-%203)
Substitute the given value of x into the equation y=2x
![y = 2 \times ( - 3)](https://tex.z-dn.net/?f=y%20%3D%202%20%5Ctimes%20%28%20-%203%29)
Solve the equation for y
![y = - 6](https://tex.z-dn.net/?f=y%20%3D%20%20-%206)
The possible solution of the system is the ordered pair (x,y)
![(x,y) = ( - 3, - 6)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28%20-%203%2C%20-%206%29)
