Question

Which ordered pair is the solution to this system of equations?

Answer 1

Answer:

(- 3, 5 )

Step-by-step explanation:

Given the 2 equations

x + y = 2 → (1)

5x + y = - 10 → (2)

Subtracting (1) from (2) term by term will eliminate the term in y, that is

(5x - x) + (y - y) = (- 10 - 2)

4x = - 12 ( divide both sides by 4 )

x = - 3

Substitute x = - 3 into either of the 2 equations and solve for y

Substituting into (1)

- 3 + y = 2 ( add 3 to both sides )

y = 5

Solution is (- 3, 5 )
