Answer:
x = -2
y=-3
(-2,-3)
Step-by-step explanation:
Both equations are equal to y
We can set them equal to each other
y = 3x + 3
y = x − 1
3x+3 = x-1
Subtract x from each side
3x+3 -x = x-1-x
2x+3 = -1
Subtract 3 from each side
2x+3-3 = -1-3
2x = -4
Divide each side by 2
2x/2 = -4/2
Now we need to find y
y = x-1
y = -2-1
y = -3
Equate both the y's to get an equation in terms of x only. Making x the subject, solve for x. Substitute the value of x in any of the given equations to find y.
3x + 3 = x - 1
y = -2 - 1 = -3
Solution is: (-2,-3)
