Question

Construct a consistent and independent system of equations that has ( − 1 , − 4 ) as its solution. Use x and y as your variables, and put your equations in the form A x + B y = C with A ≠ 0 and B ≠ 0 using the four answer boxes below. Note that there are many possible correct answers.

Answer 1

x - y = 3

2x - y = 2

Explanation:

x = 3 + y

2(3 + y) - y = 2

6 + 2y - y = 2

y = 2 - 6

y = -4

x = 3 + (-4)

x = 3 - 4

x = -1
