Final answer:
To have a solution of (3,6), we can write the equations x + y = 9 and 2x + 4y = 30.
Step-by-step explanation:
When given a solution of (3,6), we need to write two equations that have x=3 and y=6 as their solution. Let's write two equations:
Equation 1: x + y = 9
Equation 2: 2x + 4y = 30
In Equation 1, when we substitute x=3 and y=6, we get 3 + 6 = 9 which is true. Similarly, in Equation 2, when we substitute x=3 and y=6, we get 2(3) + 4(6) = 30 which is also true. Therefore, both equations have the solution (3,6).
