Answer:
B
Step-by-step explanation:
if we divide both sides of 6x + 9 = 12 by 3
(6x + 9)/3 = 12/3
2x + 3 = 4 ---> which matches choice B
So it can be easier to solve your problem
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
You have to do 45 divided by 2. Hopefully there is not tax!
Answer:
78/13 = 6 (is the price of one candle)
