Question

(08.03) Consider the following pair of equations:

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

Answer 1

combine two sequence, 3x+3=x-1. then, you can know x=-2. and put x value to any sequence. then, y= -3.
answer:(-2,-3)
