Answer:
መልሱ 78 ይሆናል ግን የጎደለው መላምት ፍጥነት ነው
Step-by-step explanation:
Left 4. Or x-4 because the way it moves
2x + y = 1
2x - 2x + y = 1 - 2x
y = 1 - 2x
y = -2x + 1
4x + 2y = -1
4x + 2(-2x + 1) = -1
4x + 2(-2x) + 2(1) = -1
4x - 4x + 2 = -1
2 ≠ -1
The solution of the problem can't be a solution because they are both parallel lines, which means they have no solution.
