Answer:
B
Step-by-step explanation:
521,370 would round to 521,400
26,839 would round to 27,800
and adding them would be
548,200
Reorder both sides
3y-6x=9
7-4y-3x=9
Multiply both sides
-6x-3y=9
6x+8y=-4
Dived both sides
11y= 5
Y=5/11
Substitute the value of Y
-3x-4(5/11)
Equals —> -14/11
Answer : (5/11 , -14/11)
Origin (0,0), x-axis left to right, y-axis up and down (vertical)
