Question

Y=5-2x 4x+2y=10 please help me

Answer 1

Hi there, this is unsolvable because both equations are equal. Have a nice day : )

Answer 2

Infinite solutions.

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

`\sf (a_1)/(a_2)=(2)/(4)=(1)/(2)\\\\(b_1)/(b_2)=(1)/(2)\\\\(c_1)/(c_2)=(5)/(10)=(1)/(2)`

⇒
`\sf (a_1)/(a_2)=(b_1)/(b_2)=(c_1)/(c_2)=(1)/(2)`

So, the line are coincident and has infinite solutions.
