Answer:
a = -⅓
b = 3
Step-by-step explanation:
-3a + b = 4
3a + b = 2
b = 4 + 3a = 2 - 3a
6a = -2
a = -2/6
a = - ⅓
-> b = 4 + 3(-⅓)
b = 4 - 1
b = 3
I may be wrong but I got x³- 2 + 12.
Answer:
The system of equations is not independent (i.e. dependent)
Step-by-step explanation:
We see that in the system of equations
3x + 6y = 12 ............(1)
x + 2y = 4.................(2)
equation (1) is exactly the same as 3 times of equation (2).
When graphed, both lines will coincide.
Therefore the system of equations is not independent (i.e. dependent)
