Answer:
A
Step-by-step explanation:
(6,4)
3x-1y=14
-y= 3x-14
y=-2x+16
sub in first equation
3x-14 =-2x+16
3x+2x= 16 +14
5x = 30
x = 6
plug in x
y=-2x+16
y = -2(6)+16
y = 4

Answer:
x=15
Step-by-step explanation:
62-2=60
60 divided by 4 = 15
First you need to know that 6% =0.06
Then multiply 175* 0.06=x
x=10.50
then subtract 175-10.50=y
y=164.50.
So the new plane ticket will cost you 164.50
