Answer:
Infinite solutions.
Step-by-step explanation:
y = 5 - 2x
2x + y = 5 ---------(I)
a₁ = 2 ; b₁ = 1 and c = 5
4x + 2y = 10
a₂ = 4 ; b₂ = 2 and c₂ = 10
[tex]\sf \dfrac{a_1}{a_2}=\dfrac{2}{4}=\dfrac{1}{2}\\\\\dfrac{b_1}{b_2}=\dfrac{1}{2}\\\\\dfrac{c_1}{c_2}=\dfrac{5}{10}=\dfrac{1}{2}[/tex]
⇒ [tex]\sf \dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}=\dfrac{1}{2}[/tex]
So, the line are coincident and has infinite solutions.
