Answer:
find the same x-value and the same y-value that satisfies both ... 1 2 3. + 4 5 6. 5 7 9 ... + (4x – 2y + 9 = 0).
Step-by-step explanation:
Answer:
x=3 y= -3
Step-by-step explanation:
Add the two equations to eliminate y
4x+2y=6
x-2y=9
-------------
5x = 15
Divide by 5
5x/5 = 15/5
x = 3
Now find y
x - 2y = 9
3 -2y = 9
Subtract 3 from each side
3-2y-3 = 9-3
-2y = 6
Divide by -2
-2y/-2 = 6/-2
y = -3
