Question

Determine the solution, if any, to the system of equations below. 8. 2y = 1 - 4x + y = 3 Show your work or explain how you got your answer.​

Answer 1

y=1/2 , x= -5/8

Explanation:

⇒
`2y=1. -4x+y=3 : y=(1)/(2) \\\left \{ {{2y=1} \atop {-4x+y=3}} \right. \\ where: y=(1)/(2) \\-4x+(1)/(2)=3\\isolate for -4x+(1)/(2) =3: x=-(5)/(8) \\y=(1)/(2) : x=(-5)/(8)`
