Answer:
The x-coordinate of the solution to this system of equations is 3
Step-by-step explanation:
Given the system of equations:
[tex]x+y = 3[/tex] ....[1]
[tex]2x-y = 6[/tex] ....[2]
Add equation [1] and [2] we have;
[tex]x+y+2x-y = 9[/tex]
Simplify:
[tex]3x = 9[/tex]
Divide both sides by 3 we have;
x = 3
Substitute in [1] we have;
3+y = 3
⇒y = 0
Solution for the given system of equation is= (3, 0)
Therefore, the x-coordinate of the solution to this system of equations is 3
