Step-by-step explanation:
Answer:
a=3
Step-by-step explanation:
x – 2y = 4
ax– 6y = 12
To have infinitely many solutions, the two equations have to be equal
Multiply the first equation by 3
3x -6y = 12
ax -6y = 12
a = 3
Answer:
12
Step-by-step explanation:
Because y=24 and x=2 you do the following:
144/24=6
Then, 6x2=12 because it is proportional
Or you could do 24/2=12 and 144/12=12
