3x - y = 2 y = 2x -9 what is x and y using substitution

xxTIMURxx [149]

3x - y = 2

y = 2x - 9

Substitute:

3x - 2x - 9 = 2

x - 9 = 2

x = 11

Substitute your answer into any equation:

y = 2x - 9

y = 2(11) - 9

y = 22 - 9

y = 13

Answer:

x = 11 ; y = 13

Jason's mom drove at 100km/hr for a 160km trip.how much longer would the trip have taken if she had driven at 90km/hr

kondor19780726 [428]

We use the formule: t=S/v. So:
+ t1= 160/100 = 8/5 hrs = 5760''
+ t2= 160/90 = 16/9 hrs = 6400''

=> t2-t1= 6400 - 5760 = 640'' = 10'40''
