Answer: (-1,-5)
Step-by-step explanation:
So to use substitution, you have to find a value of either x or y at first.
Because it says y=3x-2 and y=8x+3, you can choose either of them to act as your y variable
So let’s choose y=3x-2
We plug that into y=8x+3, so what we get is
3x-2=8x+3
Solve for x
X=-1
Now that we know the value of x, we can substitute it into any of the two equations to find y
Let’s choose y=8x+3
y=8(-1)+3
y=-5
Check:
y=3x-2
y=8x+3
-5=3(-1)-2
-5=8(-1)+3
-5=-5
-5=-5
