HELP!! Giving points: In the system of equations shown, a is the coefficient of x. The system has infinitely many solutions. Wha
t is the value of a?
x – 2y = 4
ax– 6y = 12
(Please explain your answer)
1 answer:
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
