Solve the system of equations:

y = 3x

y=x2-4

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

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
