Answer:
Step-by-step explanation:
Given system:
1) Solving the second equation for y:
- 2x + y = - 5 ⇒
- y = -5 - 2x
2) Substituting y into the first equation:
- 4x - 2y = 2 ⇒
- 4x - 2( -5 - 2x) = 2
- Correct option is a)
3) Solving for x:
- 4x - 2( -5 - 2x) = 2
- 4x + 10 + 4x = 2
- 8x = 2 - 10
- 8x = -8
- x = -1
4) Solving for y:
- y = -5 - 2x
- y = -5 - 2(-1) = -5 + 2 = -3
- y = -3
5) Ordered pair is:
