3 x – y = - 6
3 x + 6 = y
y = 3 x + 6
4 x – 3 y = - 3
4 x - 3 ( 3 x + 6 ) = - 3
4 x - 3 * 3 x - 3 * 6 = - 3
4 x - 9 x - 18 = - 3
- 5 x - 18 = - 3
- 5 x = - 3 + 18
- 5 x = 15 Divide both sides by - 5
x = 15 / - 5
x = - 3
y = 3 x + 6
y = 3 * ( - 3 ) + 6
y = - 9 + 6
y = - 3
Point with coordinates:
x = - 3
y = - 3
Name the point of intersection for the following system, if it exists.
4x – 3y = -3
3x – y = -6
