x - y = 6
a. -3
b. 0
c. 3
Answer:
The x-coordinate of of the solution of system of equations is 3.
Option (c) is correct .
Step-by-step explanation:
As the system of equations are
3x + y = 6
x - y = 6
Now multiply x - y = 6 by 3 and subtrated from 3x + y = 6 .
3x - 3x + y + 3y = 6 - 18
4y = -12
y = -3
Put in the x - y = 6
x - (-3) = 6
x + 3 = 6
x = 6 -3
x = 3
Therefore the x-coordinate of of the solution of system of equations is 3.
Option (c) is correct .
