Answer:
Option : A
Explanation:
To find the x-coordinate of the solution to the system of equations, we need to solve the system by eliminating either x or y. Let's eliminate y by multiplying the first equation by 3 and the second equation by 1:
Equation 1: 2x + y = -4 (multiply by 3)
Equation 2: 5x + 3y = -6 (multiply by 1)
Multiplying equation 1 by 3 gives us:
6x + 3y = -12
Multiplying equation 2 by 1 gives us:
5x + 3y = -6
Now we can subtract equation 2 from equation 1 to eliminate y:
(6x + 3y) - (5x + 3y) = -12 - (-6)
6x + 3y - 5x - 3y = -12 + 6
x = -6
Therefore, the x-coordinate of the solution to the system of equations is x = -6.
The correct option is: Ox=-6.
