Solve the system of equations:
y = 3x
y=x2-4
2 answers:
Answer:
y=12 x=4
Step-by-step explanation:
I will be using the elimination method to solve this
*2 y= 3x
*3 y= 2x-4.
2y= 6x
- 3y= 6x-12
-1y= -12. y= 3x
/-1 /-1. 12= 3x
y=12. /3 /3
4=x
Answer:
x = -4
y = -12
Step-by-step explanation:
Since y is 3x,
3x = 2x - 4
On solving we get x as -4
Substitute x and we get y as -12
