Answer:
y ≈ - 3.8
Step-by-step explanation:
Given the 2 equations
5x + 2y = 21 → (1)
- 2x + 6y = - 34 → (2)
To eliminate the terms in x , multiply (1) by 2 and (2) by 5
10x + 4y = 42 → (3)
- 10x + 30y = - 170 → (4)
Add (3) and (4) term by term
(10x - 10x) + (4y + 30y) = (42 - 170)
34y = - 128 ( divide both sides by 34 )
y ≈ - 3.8 ( to the nearest tenth )
