5 2 then you have 2 prime numbers and you have to multiply them together
Answer: 
Step-by-step explanation:
Given a System of linear equations, the solution of the system is the point
in which the lines intersect, where "x" is the x-coordinate and "y" is the y-coordinate.
Having the following System of equations:

You can use the Elimination method to find the value of "x":
-Multiply the second equation by 3.
- Add the equations.
- Solve for "x".
Then, you get:

3x-6=9x
3x-9x=6
-6x=6
X=-1
6x+30=3x
6x-3x=-30
3x=-30
X=-10
