Answer:
(0, -3)
Step-by-step explanation:
y = 3x - 3
y = x - 3
In the solution to the system of equations, y is the same number for both of those functions. So 3x - 3 = x - 3.
Then solve for x:
3x - 3 = x - 3
Add 3 to both sides
3x = x
Subtract x from both sides
2x = 0
Divide both sides by 2
x = 0
Now that you have x, substitute it in one of the equations:
y = 3(0) - 3
y = -3
x is 0 and y is -3, so the solution to the equation is (0, -3)
y=3x-3
y=x-3
They both equal why so you can take away the y and put them equal to each other.
3x-3=x-3
2x-3=-3
2x=0
divide 2 from both sides
x=0
The answer is 0. Hope this helps you :)
