Question:
Y= −2x + 8 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.
Answers
Hello!
Since y equals both equations they equal each other
-2x + 8 = x - 1
Add 2x to both sides
8 = 3x - 1
Add 1 to both sides
9 = 3x
Divide both sides by 3
3 = x
The answer is 3
