Answer:
We have been given the equation:
![y=-5x+30](https://img.qammunity.org/2020/formulas/mathematics/middle-school/lw4fj0e2jctu87bfd275invnzopbbsy5r3.png)
And x=10
Substitute the given x in the given equation we get:
![y=-5(10)+30](https://img.qammunity.org/2020/formulas/mathematics/middle-school/522ob0rq4asqvy6uk1hinrnaon1t38207c.png)
![y=-50+30](https://img.qammunity.org/2020/formulas/mathematics/middle-school/o2ygn1hzdz984z742ps8v7ak83ci5ys5e5.png)
On simplification we get:
![y=-20](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mqg74otd52ucnfxtgtifitajbczx808sya.png)
Required solution is: x= 10 and y=-20
The solution to the system of equation is those points that satisfy the given system of equations.
