Use substitution
Given both y values, you know that they have to be equal

3x + 3 = x - 1
2x + 3 = -1
2x = -4, divide by 2
x = -2
Now plug x value into any of the equation to find y value
y = 3(-2) + 3
y = -6 + 3, y = -3

Solution: x = -2, y = -3

Answer:

Step-by-step explanation:

Well you have to solve for X to find Y simplified.

Since both equations equal Y you can plug them together

3x+3=x-1

-x          -x

2x+3=-1

-3         -3

2x=-4

Divide -4 by 2 and you get X = -2 then plug X into both equations and boom

y= -3
