Y= 3x + 3
y = x – 1

explain how you will solve the pair of equations by substitution. show all the steps and write the solution in (x, y) form
i know it (-1,0) i just don't know how to explain it xd

I would substitute the second y value into the original equation to equal

x-1 = 3x + 3

I would then solve for x, plug x into the original value of y, and put it in a solution set.

2x=-4
x=-2

y = -6 + 3
y= -3

(-2, -3)

CHECK
-3= -2 -1
-3= -6 + 3
