from question 4? (2 points: 1 point each question)

Answer 1

The system of equations has solution (5,10).

Explanation:

We must solve the system of equations
`\begin{cases}12x+6y=120\\4x+y=30\end{cases}`.

Dividing the first equation by 6, we have that 2x + y = 20. Subtract this from the second equation to find that 2x = 10, meaning that x = 5. Plugging this back in to any of our original equations, we find that y = 10. Thus, the solution to the system of equations is (5,10).

Answer 2

x is 5,y is 10

Explanation:

those equations tell you
